   A self actuated pressure control valve uses a pitot tube which gives access for process fluid to pressurize the diaphragm which then acts to open the valve so process fluid from process line can pass through.

   Pilot operated, self-acting pressure reducing valve. Description. These have a more complex self-acting design, and operate by sensing the downstream pressure via a pilot valve, which in turn operates the main valve. The effect is a very narrow proportional band, typically less than 200 kPa.

   The flowing stream itself provides the energy needed for control. A regulator is comprised of two basic elements – a valve body and an actuator. Process pressure is used by the actuator to provide motive power needed to open or close the regulator.
