RV50-22 Relief, Differential Area Poppet (RV50-22)
A screw-in, cartridge-style, direct-acting, differential area, poppet-type hydraulic relief valve for use as a pressure limiting device in more demanding hydraulic circuits requiring low hysteresis and low internal leakage at high working pressures.
Product Operation
The RV50-22 blocks flow from ➁ to ➀ until suffi cient pressure is present at ➁ to force the poppet from its seat.
The cartridge offers smooth transition in response to load changes in common
hydraulic circuits.
Note: The RV50-22 may not be used in cross-over relief applications (back pressure
on ➀).
Product Features
• Adjustments cannot be backed out of the valve.
• Adjustments prohibit springs from going solid.
• Hardened poppet and cage for long life.
• Smooth response to pressure surges.
• Industry common cavity.
