SYMBOL
DESCRIPTION
E-RV08-22X is 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.
OPERATION:
E-RV08-22X blocks flow from port 2 to port 1 until sufficient pressure is present at port 2 to force the poppet off its seat.
FEATURES:
l Adjustments cannot be backed out of the valve.
l Variety of pressure adjustment options including non-adjustable factory preset.
l Adjustment options A, B, and C: positive stops prevent springs from going solid.

l Hardened poppet and cage for long life.
l Optional spring ranges to 248 bar (3600 psi).
l Smooth response to pressure surges.
l Industry common cavity.
l Compact size.
