SYMBOL
DESCRIPTION
A screw-in, cartridge-style, direct-acting, poppet-type, hydraulic relief valve intended for use as a pressure limiting device for common hydraulic circuit protection.
OPERATION
The E-RV10-20 blocks flow from port 1 to 2 until sufficient pressure is present at port 1 to force the poppet from its seat. The cartridge offers fast response to load changes in typical hydraulic circuits requiring low internal leakage.
NOTE: the E-RV10-20 may be used in cross-over relief applications (back pressure on 2) with the use of the "C" double back-up ring seal option.
SPECIFICATIONS:
Max. Operating Pressure: 228 bar (3300 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 foces. Consult factory for specific flow characteristic values.
Internal Leakage: 0.25 cc/minute (5 drops/minute) max. at to 80% of nominal setting
Reseat 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: - 40°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
