The 30D13 pilot-operated pressure regulator (before-valve control) is composed of the control valve, actuator and a pilot used for pressure setting. It is suitable for controlling differential pressure in the pipes of non-corrosive liquids, gases and vapors. When the before-valve pressure rises, the control valve is opened.
