Control Valves

Control valves are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers.  The Controllers compare a setpoint to a process variable whose value is provided by sensors that monitor changes in such conditions.  Mec-Tric can size control valves for customers and we stock many control valves in our inventory.  Control valves have changed over the years from air signaling (pneumatic) to more current electronic signaling.
