RV12-26 Relief, Pilot-Operated Spool (RV12-26)

A screw-in, cartridge-style, pilot-operated (two-stage), spool-type hydraulic relief valve, intended for use as a pressure limiting device in demanding hydraulic circuits which require fast response and low hysteresis.

Product Operation

The RV12-26 blocks flow from ➀ to ➁ until suffi cient pressure is present at ➀ to force the piloting relief off its seat, allowing the main (second stage) spool to shift,
opening ➀ to ➁The cartridge offers smooth transition in response to load changes in demanding
hydraulic circuits.
NOTE: The RV12-26 cannot be used in crossover relief applications.

Product Features

 Adjustments cannot be backed out of the valve.
 Adjustments prohibit springs from going solid.
 Hardened spool and cage for long life.
 Optional spring ranges to 241 bar (3500 psi).
 Fast, smooth response to pressure surges.
 Cost effective cavity.
