    Description

    self-operated before-valve pressure regulator is composed of the control valve, actuator and a spring used for pressure setting. It is suitable for controlling before-valve pressure in the pipes of non-corrosive liquids, gases and vapors. When the before-valve pressure rises, the control valve is opened.
