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.
The RV10-22 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 RV10-22 may be used in cross-over relief applications (back pressure
on ➀) with the use of the “C” double back-up ring seal option. See Ordering Table.
• 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 241 bar (3500 psi).
• Smooth response to pressure surges.
• Industry common cavity.
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 specifi c flow characteristic values.
Pressure Rise: 0.34 bar/l (5 psi/g)
Internal Leakage: 0.25 cc/minute (5 drops/minute) max. to 85% of nominal setting
Crack (Set) Pressure Defi ned: bar (psi) evident at 0.95 lpm (0.25 gpm) attained
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.
