FCV Flow Control Valve
The function of a flow control valve is to control the flow of compressed air, gases and liquids. The Proportion-Air FCV flow control valve performs this by precise closed-loop pneumatic control of the position of a valve off the seat. This angle seat valve with special seat geometry results in a linear relationship between valve position and Cv.
It does this by controlling the position of the plug off the valve seat. The output is linear and directly proportional based on command signal input, due to a parabolic design of the plug.
The FCV flow control valve is a high resolution device, providing a resolution of ±0.3 percent of a full stroke (full stroke = one inch).
It compares the command signal input from a customer’s computer or PLC with feedback from a built-in electronic linear variable differential transducer (LVDT).
