SYMBOL
DESCRIPTION
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
The E-RV10-22 blocks flow from port 2 to port 1 until sufficient pressure is present at port 2 to force the poppet from its seat. The cartridge offers smooth transition in response to loads in common hydraulic circuits.
Note: the E-RV10-22 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 can not be backed out of the valve.
* Adjustment options A, B: positive stops prevent springs from going solid.
* Optional spring ranges to 248 bar (3600 psi).
* Rapid response to pressure changes.
* Compact size.
SPECIFICATIONS:
Max. Operating Pressure: 241 bar (3500 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.
Internal Leakage: 0.25 cc/minute (5 drops/minute) max. at to 80% of nominal setting
Crack Pressure Defined: pressure evident at 0.95 lpm (0.25 gpm) attained
Release Pressure: Nominal 85% of crack pressure
Standard Spring Ranges: Due to manufacturing tolerances, it may be possible to adjust the valve either lower or higher than the nominal ratings shown below.
Temperature: - 30°C ~ +120°C (with Standard Buna N seals)
Fluids: Mineral-based or synthetics with lubricating properties at viscosities of 7.4 to 420 cSt (50 to 2000 sus);
Cavity: VC10-2
