Thermostatic radiator valve is commonly referred to as TRV and this is a self-regulating valve fitted to hotwater heating system radiator, to control the temperature of a room by changing the flow of hot water to theradiator. Thermosta...
Analyze the application to determine which valve is best suited for installations, keeping in mind the service for which the valve is recommended. Before installing the correct valve, review the installation instructions to prevent damage to the valv...
In certain fluid power systems, the supply of fluid to a subsystem must be from more than one source to meet system requirements. In some systems an emergency system is provided as a source of pressure in the event of normal system failure. The emerg...
A Gate Valve, or Sluice Valve, as it is sometimes known, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. They are so-named because the part that either stops or allows flow through the valve acts somew...
In fact a counterbalance valve is an improved pilot operated check valve. An important and major difference between these two valves is: - the opening pressure of a pilot operated check valve depends on the pressure (applied by the load) behind the v...
Have you ever taken a shower that was perfectly adjusted for the right temperature, only to have someone somewhere else in the house turn on a tap or flush the toilet and completely mess up your perfect temperature shower? If you have, you may wish t...
A throttle valve is a device installed in the fuel systems of engines which regulates the pre-determined amounts of fuel and air which reach the combustion areas of the engines. The amount of fuel and air that goes into the combustion chamber regulat...
Dump valves are fitted to the engines of turbo charged cars and sit between the turbo outlet and the throttle body. When transitioning from a boosted state to a closed throttle state (as in between shifts), due to inertia, the turbo continues to pres...
A piston valve is a device used to control the motion of a fluid along a tube or pipe by means of the linear motion of a piston within a chamber or cylinder. In fact, the piston valve is a variant of the conventional globe valve, with the traditio...
A needle valve is a type of valve having a small orifice and a threaded, needle-like plunger. It allows precise regulation of flow, although it is generally used for, and is capable of, only relatively small flow rates. Needle valves are similar i...
A diaphragm valve is a shutoff or control valve with a flexible membrane, or diaphragm, which seals the valve completely or partially once the valve is engaged. Once the actuator is engaged, a stem within the valve pushes a plug or compressor against...
The globe valve is named after its shape. Its body has an interior partition, and the valve inlet and outlet centers are inline. This configuration forces a change in the direction of flow in the form of an S. A Globe valve is a device for regulating...
Have you ever used an industrial air hammer? Have you checked on your automotive starter system at one point or another? Have you ever seen an electric bell assembly? If you answer yes to any of these questions, then you probably know what a solenoid...
There are three valve-related accidents have taken place in the past month. Valve in oxygen cylinder the culprit in 747 explosionIn July 29, 2008, a valve from an oxygen cylinder blasted a hole at least 20 centimeters in diameter in the floor of the ...
