PRESSURE CONTROLS

RV10-23 Relief, Pilot-Operated

DESCRIPTION

A screw-in, cartridge-style, pilot-operated, two-stage, hydraulic relief valve intended

for use as a pressure limiting device in demanding hydraulic circuits which require

fast response, low hysteresis, low leakage and low pressure overshoot.

OPERATION

The RV10-23 blocks ﬂ ow from ➀ to ➁ until sufﬁ cient pressure is present at ➀ to

force the pilot stage open, allowing the main stage to shift, opening

➀ to ➁.

Note: The RV10-23 may be used in cross-over relief applications, however, it is not

recommended for use as in parallel cross-over relief or anti-cavitation applications.

Consult factory for proper ﬂ ow path connections.

FEATURES

• Adjustments cannot be backed out of the valve.

• Hardened spool and cage for long life.

• Fast response.

• Industry common cavity.
