RV11-12 - Relief Valve
Spool, pilot operated
190 L/min (50 USgpm) • 350 bar (5000 psi)
Operation
When the inlet pressure
exceeds the setting of the
valve, the pilot section opens,
causing a small flow across the
orifice in the main spool.
The subsequent pressure drop
moves the spool against a light
spring opening a ring of radial
holes in the sleeve, allowing
relief flow to tank.
Features
High accuracy of pilot operated
design. Hardened working
parts give long, reliable,
trouble-free life. Cartridge
construction for installation into
your own manifold.

Description
To limit pressure in a system.
Good for continuous duty and
accurate pressure control with
constant or varying flows.
