A Control Valve is a device capable of modulating flows at varying degrees between minimal flow and full capacity in response to a signal from an external control device to the valve’s actuator. The valve modulates flow through movement of a valve plug in relation to the port(s). The actuator, which can be pneumatically or electrically operated, directs the movement of the stem as dictated by the external control device.
