RV10-26 Valve

RV10-26 Valve symbol

A screw-in, cartridge-style, pilot-operated, two-stage, spool-type hydraulic relief valve, intended for use as a pressure limiting device in demanding hydraulic circuits which require fast response and low hysteresis.

The RV10-26 blocks flow from 1 to 2 until sufficient pressure is present at 1 to force the pilot relief off its seat, allowing the main stage to shift, opening 1 to 2. The cartridge offers smooth transition in response to load changes in demanding hydraulic circuits
Note: The RV10-26 cannot be used in cross-over relief applications.

• Adjustments cannot be backed out of the valve.
• Adjustments prohibit springs from going solid.
• Hardened spool and cage for long life.
• Optional spring ranges to 210 bar (3000 psi).
• Rapid, smooth response to pressure changes.
• Industry-common size.

Operating Pressure: 240 bar (3500 psi) maximum
Flow: up to 113.6 lpm (30 gpm); 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: 115 cc/minute (7 cu. in./minute) max. to 85% of nominal setting
Crack Pressure Defined: bar (psi) evident at 7.6 lpm (2.0 gpm) attained
Reseat Pressure: Nominal 90% of crack pressure
Standard Spring Ranges: 6.0 to 27.6 bar (100 to 400 psi);
   10.3 to 103.4 bar (150 to 1500 psi);
   27.6 to 206.9 bar (400 to 3000 psi)

Temperature: -40° to 100°C (-40° to 212°F) with Buna seals;
   -26° to 204°C (-15° to 400°F) with Fluorocarbon seals
Filtration: See page 9.010.1
Fluids: Mineral-based or synthetics with lubricating properties at viscosities of
   7.4 to 420 cSt (50 to 2000 sus); See Temperature and Oil Viscosity, page 9.060.1
