The RP 814 pressure reducing valves are pilot-controlled control valves of tubular design consisting of a main valve, a pilot valve connected with the main valve via pipes and a restrictor assembly with built-in strainer. The valve cone is fitted with a metallic seal. When the pipeline is depressurised the main valve is kept closed by a preloaded spring. To open the valve a pressure difference (p1 – p2) of at least 2 bar is required. When the outlet pressure is below the set pressure the pilot valve is kept open by its spring. The control medium can flow towards the valve outlet. Restrictor D1 produces a pressure drop causing the outlet pressure to be almost equal to the pilot pressure in the main valve. The inlet pressure overcomes the outlet pressure and closing force of the spring and opens the main valve
