Open A Sink Mixer Stuck Gate Valve

Posted on April 24, 2012 by admin

Sink Mixer
Gate valves Sink Mixer are available in two types, wedge-shaped and parallel, each with different functions. Wedge-shaped gate valves are made of two inclined seats and a slightly misaligned gate that allows for tight shut-off functionality. Parallel gate valves utilize a flat disc between two parallel seats, one upstream and one downstream, to control liquid flow.
Identify the valve
1 Identify whether you’re dealing with a gate valve or not. A gate valve is typically wedge-shaped.
2 Gate valves allow water to flow in a straight line, and the valve acts like a gate to stop the flow of water.
3 When Brass Gate Valve are open wide, they leave an opening for water flow through the valve that is the same size as the pipe entering and exiting the valve.
Identify the problem
4 Cut off the water supply to the defective valve if possible to isolate your work area and reduce the risk of creating additional leaks or repairs.
5 Eliminate and examine any outside factors that could be causing the valve to malfunction, such as a damaged water line or excessive cold.
6 Place a bucket beneath the offending valve in case getting it unstuck involves its ultimate removal. Gate valves that have not been opened and closed periodically can suffer excessive buildup, affecting the valve’s operation.
Fix the problem
7 Apply a light coat of 3-IN-ONE oil or another type of penetrating oil to the valve, wiping off the excess. You must get the oil onto the valve threads. Tap the valve with a small hand tool, such as a hammer or wrench, to see if the valve will give.
8 Attach an adjustable wrench or channel locks over the valve handle, using a rag or non-slip gloves to work the tool and give you additional leverage. Keep the surface stable with another pipe wrench so as not to twist any of the surrounding pipe or fittings.
9 Warm up handle with a hair dryer or (very gently) with a blowtorch if excessive cold is the culprit for the stuck valve. Use extreme caution with a blowtorch. You want to keep yourself and your property safe.

Apply Pex Fittings

Posted on April 11, 2012 by admin

Brass Pex Fittings
People get in a hurry when crimping Brass Pex Fittings, which leads to some common mistakes. Among the most common mistakes are using scratched or scarred pipe, failing to hold the crimp tool at the proper 90-degree angle and making a crooked cut in the pipe. The crimp ring removal tool, designed to aid in salvaging costly PEX fitting, is easy to use. Learning how to use the tool takes only minutes, and is well worth the time.
1 Finding a PEX certification class was the most difficult part of this job. It took a few weeks to find a class, but it was free and only took about an hour. Check local requirements to determine if you actually need this certification. Many areas require certification to purchase PEX and pass county inspection. The class covers the proper application of fittings, a some history, and a little about the tubing.
2 Determine the type of fittings you will use. The crimp style fittings of Automatic Sensor Faucet come in both engineered plastic and brass and have rings that are separately purchased. Slide-on fittings also come in plastic and brass.
3 To apply a crimp fitting, cut your PEX tubing squarely, insert the barb completely into the PEX tubing, then slide the ring over the top. To apply a slide-on fitting, cut your PEX tubing squarely, mark the tubing about a half an inch from the end and slide into the fitting. The mark allows you to make sure the tubing was seated properly in the fitting.
4 Place a hydraulic crimping tool around the ring and pump 4-6 times to tighten. If you do not have a hydraulic tool, place the PEX fitting tool around the ring and squeeze. If you make a mistake with a crimped fitting you must cut it off and start again. There is a simple horseshoe shaped tool used to remove slide on fittings.
5 When all fittings are done, pressure test your work using a pressure gauge and air compressor. The line should hold pressure overnight.
6 Use a mixture of soapy water to test for leaks if the pressure did not hold. Small bubbles will form around air leaking from a joint.

Introduction To Brass Gate Angle Valve

Posted on March 27, 2012 by admin

Brass Angle Valve
Though the basic function of these valves is to control the flow of liquid, it can seldom be used to regulate the flow of liquid in a continuous manner. Brass Angle Valve is usually used to completely shut down or open the duct.
Most of the valves are designed specifically to allow free flow of liquid or to shut down the flow completely. However, there are valves which can be utilised to regulate the flow of liquid but it operates in a more complex manner and seldom lasts longer.
These valves are more often used to control the flow of liquids which are thicker in consistency such as cream, oil and so forth. Nevertheless, it can seldom be utilised for controlling the flow of clean liquids.
Brass Gate Valve is essential for applications where a shut-down mechanism is vital. These valves are reliable and efficient for timely control of liquid flow. Today a variety of valves can be bought from online and offline stores at reasonable price rates. Valves of different sizes and designs can be easily bought from a number of online stores at discounted rates.
The featured part of the gate valve is the wedge disc which also called as the gate segment. It is used to open or close totally to control the flow as its moving direction is vertical with the flow direction. Commonly, the gate valve is not proper to be used to regulate the flow. And the seal is definitely necessary to ensure the operation, for which many kinds with specified specifications are available. The type of self-sealing refers to that the pressure from the medium is used to achieve the function of sealing. And the other type is the one which requires the external force to shut off the gate segment in order to ensure the good tightness. And in terms of the shapes formed by the two sealing faces, there are rigid gate and flexible gate available.
And it is certain that there exist required standards on many aspects. They aim to make the valve perform safely and effectively to withstand the available temperatures and pressures. And there are many applicable driving modes, such as the manual mode, bevel gear mode and such others. Similarly, many kinds of media can be controlled by the gate valve. Generally speaking, the gate valve is popular either in the industrial process or in the daily life. There are some appreciated advantages of this term, such as the fluid resistance, convenient opening and closing, unrestricted flow of medium, simple structure, good manufacturing process and wide range of the applications.

Bathtub Faucet Gate Valves Different Types That Exist In The Market

Posted on March 19, 2012 by admin

Bathtub Faucet
Brass Gate Valve is one of the most popularly and widely used valves for domestic and industrial purposes. This valve is specifically used to obtain uninterrupted flow of water. Used mostly in isolated applications, this valve is greatly preferred because once the valve is in an open position; there is complete drop in the pressure which is due to the retraction of the gate into the bonnet.
According to specific designs, this valve is divided into different categories. The most commonly used valves include the flexible wedge and the solid wedge gate valve. There are different types of flexible wedge valves which utilises twin disc parts which are flexible. The parallel side valve is one of the most commonly and widely used flexible wedge valve. These valves are prominently used in stem systems as it can withstand expansion and contraction under varying climatic conditions.
Gate Valves in Different Materials
There are many popular materials that are used for manufacturing it. Those made of bronze and brass are among the popular varieties. Various forms of iron, including cast iron and ductile iron, too are used for it manufacturing. Among the different varieties of steel, stainless steel, forged steel, cast carbon steel and alloy steel are the quality materials for durable Bathtub Faucet gate valves. Finally, there are valves made of gun metal that you can obtain from different manufacturers.
Rising and Non Rising Stem Gate Valves
The most important way to classify it is on the basis of the behavior of the stem attached to these valves. A rising stem gate valve is one in which the stem rises when the valve is rotated to open. However, this type of valve may not work when there is less vertical space. For example, rising stem valves are not suitable for underground operations. Non rising stem valves are used in such situations. Stems don’t rise during the operation of these valves.
Gate Valves with Different Bonnet Styles
It can also be classified on the basis of the type of bonnet they have. Screw-in bonnet style it is small in size and used for simple applications. On the other hand, high pressure applications make use of large valves with bolted bonnets. For extremely high pressure applications, the use of its with pressure seal bonnet is popular for offering high safety. A valve with union style bonnet is another option and used for applications where regular inspection is required.
Wedge and Parallel Gate Valves
Depending upon the shape that the gate valve faces form, these valves can be divided into wedge and parallel valves. Wedge valves can be further classified into single gate type, dual gate type and flexible gate type. Parallel gate valves too can be classified into single and double plate types.

Automatic Sensor Faucet Work Principle

Posted on March 13, 2012 by admin

Automatic Sensor Faucet
Biggest reasons for the public lavatories to have them, is the fact that they are hygienic. No-one is touching the faucet, so there is no problem of transmitting bacteria when you wash your hands. Normally you would use your hand to make the water flow, and after you would close the tap with the washed hands. You just used dirty hands to open the tap, and you are getting those germs in your hands again. A Automatic Sensor Faucet does not have this problem as it is controlled by a sensor that activates when you move your hands towards it.
Sensor
The sensor in a touchless faucet typically is located at the lip or base of the spout. It isn’t a motion sensor but a presence sensor designed to detect the presence of hands under the spout and turn on the faucet. When you remove your hands, the sensor tells the faucet to turn off. Most faucet sensors use a tiny infrared light mounted next to an infrared detector. When your hands come within a few inches of the lip of the spout, infrared light bounces off your skin to the detector, which sends a signal that turns on the faucet valve. Some faucet models use an ultrasonic field sensor that turns on the faucet valve when your hands disrupt the field.
Solenoid Valve
The Self Closing Basin Taps typically controls a solenoid-activated diaphragm valve. The solenoid is an electromagnet that can push or pull, depending on electric polarity. Diaphragm valves use a rubber-like disc to control water flow. The valve is normally held closed, but in response to a sensor signal that hands are present, the solenoid pulls the valve open so water can flow out the spout, then pushes the valve closed again when the sensor says the hands are gone. Most touchless faucets dispense only warm water, but some models can provide hot or cold water.
Power Source
All touchless faucets require a power source. Some models draw power from dry-cell batteries, while others use a low-voltage current from an AC transformer. Electricity powers the sensor, control electronics and water valve. Battery-powered faucets use latching solenoid valves that stay in the open position without further electric current until a spurt of power pushes them back to the closed position. Transformer-powered faucets use continuous electric current to hold the solenoid valve open.
Spouts
Touchless faucet spouts, which hold all the working parts, are made of zinc in cheaper models, while the high-end models are made of brass. They may be plated with nickel or chrome for durability and appearance. The spouts may be machined, die cast or sand cast. There are different styles of spouts for standard bathroom or kitchen use, lab sinks, bar sinks and food service sinks. The spout also is where aesthetics come into play. The shape and finish of the faucets’ spouts are major reasons buyers choose one touchless faucet over another.

Cut Stainless Steel Flexible Hose

Posted on March 6, 2012 by admin

Stainless Steel Flexible Hose
Stainless Steel Flexible Hose is a rubber hose that contains a braided steel center. The diameter of the hose depends on the thickness of both the rubber and the steel braiding. Steel braided hoses provide a strong, pressure resistant hose for use in a variety of applications. Everything from hydraulics to art may utilize steel braided hoses. But unlike regular rubber hoses, steel braided hose cannot be easily cut with a utility knife or snips. Therefore certain other tools are necessary to cut the rigid steel braiding in the tube.
Two Ways for a Clean Cut
According to expert auto mechanics, if you see the steel braided hose to have uneven and unravel braids on one end, stop trying to connect it. Instead, cut the hose again so it will get a clean edge. Remember that when cutting a steel braided hose, the main objective is to cut it as clean as possible. Auto enthusiasts use the following steps to easily achieve the cleanest cut possible:
Wrap the part to be cut with a tape. Plastic electrical tape, a duct tape, or any tape you have can be used for this. Most people use duct tape. Wrapping the part with a tape will prevent the braids to unravel, giving you the cleanest cut possible. Two tape wraps will be enough.
Cut the Stainless Steel Braided Hose. Use the finest cutter you can find. Again, remember that your goal is to end up with the cleanest cut possible. The best tool for the job is a hacksaw. Use the finest blade for this or at least that one with 32 teeth for every inch. Aside from a hacksaw, you can also use an abrasive disc cutter.
Another way to do this is by following the steps below:
Clamp the hose using a worm-drive hose clamp. This can squeeze the hose and ready it for the assembly.
Insert a dowel into the hose. The wooden dowel will make the hose sturdier for a cleaner cut.
Cut the steel braided hose. Again, use the finest and the sharpest tool possible. Use the same tools recommended for the tape-wrapping technique.
Any of these two will do a great job as long as you’ll religiously follow the steps provided.

Test A Fuel Pump Bibcock

Posted on February 27, 2012 by admin

Bibcock
Brass Y Check Valve come in a range of diameters for different kinds of piping. They are also tested to determine their load rating, determining how much pressure is required to break the valve. As a general rule, experts recommend purchasing check valves with pressure ratings which exceed the potential pressure which can be generated by a system, ensuring that the check valve will hold up even if the system reaches a critical point of pressure.
1 Park the vehicle on flat ground and set the parking brake. Chock the wheels on the end of the vehicle opposite the fuel pump. Remove the fuel pump fuse and start the vehicle. Allow the vehicle to run until it stalls. Crank the engine for five seconds to remove residual pressure from the fuel system.
2 Raise the vehicle using a jack and support it securely on jack stands to access the fuel pump. Use a screwdriver, wrench or fuel line removal tool to disconnect the fuel line on the outlet port of the fuel pump. Beware of spraying or leaking fuel when disconnecting the fuel line.
3 Turn the check valve Bibcock in the end of the fuel pump counterclockwise with an open-end wrench until it can be removed from the pump. Blow compressed air through both ends of the check valve. Verify that air can only travel through the check valve in one direction and is completely blocked in the other direction. Replace the check valve if air can pass through it in both directions.
4 Thread the old, or new if necessary, check valve into the pump and turn it clockwise until it’s finger tight. Turn the check valve an additional 1/4 turn clockwise with an open-end wrench. Reconnect and tighten the fuel lines. Raise the vehicle with a jack, remove the jack stands and lower the vehicle to the ground. Remove the wheel chocks.
5 Reinstall the fuel pump fuse and start the vehicle. Allow the vehicle to run until the radiator fan cycles on and off. Turn off the vehicle. Check the fuel lines for leaks and tighten any leaking connections. Wait 10 minutes and start the car. Check the fuel system for proper operation. Continue troubleshooting the fuel system if the check valve functions correctly but a problem still exists.

Replace Brass Gas Valve

Posted on February 21, 2012 by admin

Brass Gas Valve
Brass Gas Valve control the flow of natural gas that moves from a gas main line to a furnace. As of 2010, most new gas furnaces come equipped with natural gas valves. When a furnace is installed, the natural gas valve is calibrated so it properly senses the amount of gas, called gas pressure, that the natural gas lines are supplying it with.The gas valve receives a signal from the gas furnace control board or module. This small computer tells the gas valve what the gas pressure is. The control board closes the safety switches in the furnace safety circuit and readies the main burner for firing. The control board then sends a signal that tells the valve to open so gas can reach the manifold and main burner.
1 Switch off the electrical power and the main gas line.
2 Remove the gas input from the furnace with the wrench. Smell for any gas odor. If you detect gas either by smell or if you feel gas coming out of the pipe, re-attach the input to the valve, leave the electrical switched off and call a professional.
3 Unplug the wiring harness from the old valve. Place the pipe wrench on the flange or port where you disconnected the incoming gas. Rotate the valve counter-clockwise to remove it from the output pipe. Set the old valve aside.
4 Install flange adapters if the replacement valve’s input and output ports do not match the size of the input and output pipes. Insert the O-ring in the flange groove; the O-ring faces the valve. Use the included hex screws to attach the flange to the valve. Repeat for the other port if necessary.
5 Note the “Outlet” marking on the top of the Brass Gate Valve. Orient the valve so that the outlet port on the valve lines up with the outlet pipe for the furnace or water heater. Apply pipe compound to the threads of the outlet pipe on all but the last two threads so that the threads that first touch the valve have no pipe compound on them.
6 Turn the valve clockwise onto the pipe with the pipe wrench. Place the wrench on either the flange or the square valve casing where the flange would attach. Tighten the valve in place.
7 Connect the input pipe to the input port on the valve. Apply pipe compound in the same way to the threads of the input pipe. Twist the input pipe clockwise into the input on the valve until it is tight.
8 Mix the dish soap with water and brush it on to the connections. Turn on the gas and look for bubbles in the soap. If there are any bubbles, tighten the connections. Continue until there are no bubbles showing. Wipe off the pipes and the valve.
9 Plug in the wiring harness and switch on the power. Switch the valve into the “On” position. Light the pilot light per the instructions for your furnace or water heater.

Steps To Install Brass Check Angle Valve

Posted on February 14, 2012 by admin

Brass Check Valve
There can be different types of control valves. The most versatile and common types are Brass Angle Valve and sliding-term globe. These are suitable for a wide variety of process applications. There are three common methods with which one can install the control valves in the pipelines such as screwed pipe threads, welded end connections and bolted gasket flanges.
The tools for the manufacturing job are the copper pipe cutters, tape measure, Teflon tape, compression fitting, flexible supply tube and the angle valve. Firstly, it is important to turn off the main water supply and turn on all the water Valves in the house immediately follow. Such step is done to let the existing water in pipelines drain. Secondly, find the place for installation of the angle Brass Check Valve and then disconnect the water supply. And if the water supply is in a soldered pipe fitting, it is helpful to use a pair of copper cutters to cut 2 inches from the base of the installed location. Thirdly, the compression nut and compression ring is slide from the angle valve with the threaded side faced toward the open end in very sequence.
Fourthly, the Teflon tape is used to tape the end of the pipe. Then, tighten the nut, ring together with the installed angle valves tightly. Afterwards, flexible supply tube should be attached into the other side of the required valve. All the other compression fittings should be totally tightened to their own spaces. But it is necessary to catch out the over-tightening. Otherwise, damages to the parts or poorness in seal performance would result in. When all work has been down, turn on the main water supply to inspect for leakage. In the end, turn on the angle valve to check for the expecting shutting off performance.
