Description

Self-acting back pressure regulators are simple control valves offering accurate control while being easy to install and maintain. They control the pressure upstream of the valve without requiring pneumatic or electrical control
elements.
The RP 810 pressure reducing valve is a pilot-controlled control valve consisting of a main valve, a pilot valve complete with restrictor assembly and
built-in strainer mounted on the cover of the main valve, non-return valve
and restrictor valves. The valve cone can be fitted with a soft or metallic seal.
When the pipeline is depressurised the main valve is kept closed by a preloaded spring. 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 piston. The inlet pressure overcomes the outlet pressure and closing force of the spring
and opens the main valve.
As soon as the outlet pressure has reached the set pressure, the pilot valve
restricts the flow. This causes the pilot pressure to rise and push the main
valve piston into a controlling position. The restrictors D1 and D2 are used to
optimise the control characteristics. The bypass fitted with a non-return valve
ensures quick closing.
When the outlet pressure exceeds the set pressure the pilot valve closes.
The pilot pressure is equal to the inlet pressure. The main valve closes as
the piston diameter is greater than the valve seat. The spring also forces the
valve to close.
These valves are no shut-off elements ensuring a tight closing of the valve.
In accordance with DIN EN 60534-4 and/or ANSI FCI 70-2 they may feature
a leakage rate in closed position in compliance with the leakage classes III
or V.
