DESCRIPTION
E-RV08-22 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-RV08-22 blocks flow from port 2 to port 1 until sufficient pressure is present at port 2 to force the poppet off its seat. The cartridge offers smooth transition in response to load changes in common hydraulic circuits.
NOTE: the E-RV08-22 may be used in cross-over relief applications (back pressure on 1) with the use of the "C" double back-up ring seal option.
FEATURES:
* Adjustments cannot be backed out of the valve.
* Adjustment options A, B, and C: positive stops prevent springs from going solid.
* Hardened poppet and cage for long life.
* Optional spring ranges to 221 bar (3200 psi).
* Smooth response to pressure surges.
* Industry common cavity.
* Compact size.
SPECIFICATIONS:
Working Pressure: 221 bar (3200 psi)
Flow: The Performance Chart illustrates flow handling capacity at maximum setting for each spring range option. Pressure rise will vary with spring (range) and with setting within range due to flow forces. Consult factory for specific flow characteristic values.
Maximum Internal Leakage:
Crack Pressure Defined: Pressure evident at 0.95 lpm (0.25 gpm) attained
Reseat Pressure: Nominal 90% of crack pressure
Standard Spring Ranges: Due to manufacturing tolerances, it may be possible to field-adjust the valve higher than the norminal ratings shown below.
Temperature Range: - 40°C ~ +120 °C (with Buna N seals)
Fluids: Mineral based or synthetic hydraulic fluid with lubricating properties at viscosities of
