RV10-22 Valve

SYMBOL:
RV08-22 Valve symbol

DESCRIPTION
A screw-in, cartridge-style, direct-acting, differential area poppet-type, hydraulic relief valve
intended for use as a pressure limiting device in more demanding hydraulic circuits requiring
low hysteresis and low internal leakage.

OPERATION
The RV10-22 blocks flow from 2 to 1 until sufficient pressure is present at 2 to force the
spring-opposed 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 1)
with the use of the “C” double back-up ring seal option. See ordering options below.

FEATURES
• Adjustments cannot be backed out of the valve.
• Adjustments 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).
• Rapid response to pressure surges.
• Industry-common size.

RATINGS
Operating Pressure: 241 bar (3500 psi) maximum
Flow: 113.6 lpm (30 gpm) maximum; see performance chart for flow handling capacity at max.
   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.
Pressure Rise: 0.34 bar per liter (5 psi per gallon)
Internal Leakage: 0.25 cc per minute (5 drops/minute) max. to 85% of nominal setting
Crack (Set) Pressure Defined: 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.
