PRESSURE CONTROL
Pressure reducing valve RP 810 Eck
Pilot-operated pressure reducing valve

Technical data
echnical data

DescriptionDescription

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 pressure reducing valve RP 810 Eck is a pilot-operated regulating valve
consisting of a main valve with a pilot valve fixedly mounted on the cover
and a throttle block with integrated strainer, non-return valve and throttle
valves. The valve cone is either metallic or soft-sealed.
Once the outlet pressure has reached the pre-set nominal value, the pilot
valve starts to throttle. In doing so, the control pressure rises and pushes the
main valve piston to a regulating position. The throttles D1 and D2 serve to
optimise the regulating behaviour. The bypass equipped with a non-return
valve brings about rapid closure.
If the outlet pressure exceeds the nominal value, the pilot valve closes. The
control pressure is equivalent to the inlet pressure. The main valve closes
because the piston diameter is larger than the valve seat. In addition, the
spring also has a closing effect.
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.
