PRV2-10 - Pressure Reducing/Relieving Valve
Spool, pilot operated
38 L/min (10 USgpm) • 240 bar (3500 psi)
Operation
This valve is normally open
allowing inlet oil to pass to the
regulated line until the outlet
(regulated) pressure exceeds
the setting of the pilot section.
When this setting is achieved
a pilot flow occurs, causing a
pressure imbalance across the
main spool, which then moves
throttling the inlet flow
and preventing any further
pressure rise in the regulated
line. If any external force
causes the regulated pressure
to rise more than 5-10% above
the setting, the main spool
moves back further, opening
the regulated port to the tank
line, thus working as a relief
valve.
Features
Cartridge construction with
hardened, ground and honed
working parts giving smooth,
stable operation over all
pressure ranges.

Description
This is a pilot operated
screw in cartridge pressure
reducing / relieving valve. The
valve maintains a constant
outlet pressure in hydraulic
sub-systems regardless of
fluctuations in the primary
system. In addition to this it
will act as a relief valve if the
pressure in the sub-system
rises higher than the setting of
the valve directing excess fluid
to tank.
