CONTROL VALVE BASICS – SIZING & SELECTION Introduction A control valve is a power operated device capable of modulating flow at varying degrees between minimal flow and full capacity in response to a signal from the controlling system. Control valves may be broadly classified by their function as “on-off” type or “flow regulating” type.

Control valves are an increasingly vital component of modern manufacturing around the world. Properly selected and maintained control valves increase efficiency, safety, profitability, and ecology. The Control Valve Handbook has been a primary reference since

For applications in coal fired power plants, combined cycle power plants, industrial power plants, other steam boiler applications and/or turbine bypass applications. The Safety Relief Valve SiZ is generally used to safeguard the main steam and re-heater systems of power plants. It can be used as a controlled safety valve or

03-01-2022· Gate valves are used in wastewater plants, power plants, and process plants for shut-off and for isolating service. Gate valves are usually designated as rising-stem and non-rising stem designs. The advantage of rising-stem valves is that they permit easy visualization as to whether a valve is open or closed.

a power source of some type, such as electricity or compressed air in order to operate. A pressure relief valve must be capable of operating at all times, espe-cially during a period of power failure when system controls are nonfunctional. The sole source of power for the pressure relief valve, therefore, is the process fluid.
