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 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.
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 in which opening and closing forces
are in balance.
When the outlet pressure exceeds the set pressure the pilot valve closes.
The pilot pressure is equal to the inlet pressure. The forces acting on the piston are in equilibrium and the main valve is kept closed by its spring.
The restrictors are used to optimise the control characteristics. The bypass
line around D2 which is fitted with a non-return valve, ensures quick closing.
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.
