How does a temperature control valve work?
Thermostatic Control Valves As the temperature of the fluid changes, it causes the wax to expand or contract which, in turn, slides the valve up or down, opening or closing ports.
How does a steam control valve work?
Steam is supplied at a specific pressure to the upstream side of the control valve through which it passes to a heat exchanger, also operating at a specific pressure. Steam passes through the control valve and into the steam space of the equipment where it comes into contact with the heat transfer surfaces.
What is a thermal control valve?
Thermal control valves provide a means to control the temperature of coolant at a particular point in a system to a defined value. The valves produced by PDT are passive, thermostatic-type valves which do not require electrical power or a control circuit to operate.
What is a TCV valve?
The TCV standard temperature control valves are used in hot water supply systems to mix hot and cold water to a controlled outlet temperature, reducing the risk of exposure to excessively hot water.
What is thermostatic temperature control?
Thermostatic temperature control systems consist of a thermostat plus some sort of heater and/or cooler. If temperature is below the set point, the heater is on and the temperature rises. When the rising temperature passes the set point, the thermostat switches the heater off and temperature falls passively.
What is a steam valve?
A steam valve, is a type of valve used to control the flow of steam from the source, e.g the boiler to the point of use, steam valves are also used to control the pressure of the steam.
What is steam control valve?
The steam control valve is one of the most basic and indispensable components of the steam system, and plays a very important role in the quality of the products that the plant is producing. Steam control valves not only control the pressure, but also the temperature in process applications.
How does a temperature regulator work?
It works by setting up a hysteresis band. For instance, a temperature controller may be set to control the temperature inside of a room. The controller would then send a signal to increase the applied heat to raise the temperature back to the setpoint of 68°. Once the temperature reaches 68°, the heater shuts off.
What is GPV valve?
GPV (Gas Passivation Valve) – Helium latch/venting valve for end of life passivation.
What is an XV valve?
An XV valve is an in/off valve mainly used to provide tight closing conditions (TSO). They can be operated by solenoids (if used in ESD locks) or manually. To do this, a control valve is necessary for discharge of the pump to the bottom of the vessel.
