Control Valves

Control valves modulate the flow of fluids (gas and liquid) to control process setpoints such as flow rate, pressure, temperature and level. There are various designs of control valves to meet the requirements of specific applications. Typically, a 4-20mA or 3-15 psig pneumatic control signal is sent from a feedback controller (standalone digital, DCS digital or PLC digital) to an actuator mounted on the valve. The most common actuators are pneumatic using air to operate the actuator that then modulates the valve position to maintain the desired setpoint. Additionally, electric motor driven actuators and hydraulically driven actuators are used to modulate control valves.
