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.
