RV10-26 Valve

U.S. Patent 7,137,406

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 cartridge offers smooth transition in response to load changes in demanding
hydraulic circuits.

The RV10-26 blocks flow from 1 to 2 until sufficient pressure is present at 1 to force the piloting relief
off its seat, allowing the main (second stage) spool to shift, opening 1 to 2.
NOTE: The RV10-26 cannot be used in crossover relief applications.

• Adjustments cannot be backed out of the valve.
• Adjustment options A, B and C: positive stops prevent springs from going solid.
• Hardened spool and cage for long life.
• Optional spring ranges to 207 bar (3000 psi).
• Fast, smooth response to pressure surges.
• Industry common cavity.

Operating Pressure: 344 bar (3500 psi)
Proof Pressure: 517 bar (7500 psi)
Burst Pressure: 1038 bar (5000 psi)
Flow Rating: 113.6 lpm (30 gpm) at max pressure
Relief Pressure Setting Defined: bar (psi) evident at 7.57 lpm (2 gpm)
Internal Leakage: 0.53 ml per minute (10 drops/minute) max. to 80% of nominal setting
Crack Pressure Defined: bar (psi) evident at 7.6 lpm (2.0 gpm) attained
Reseat Pressure: Nominal 90% of crack pressure
Relief Pressure Range:
6.9 to 207 bar (100 to 3000 psi); Due to manufacturing
   tolerances, it may be possible to adjust the valve either lower or higher. If the
   valve is adjusted beyond the recommended maximum pressure range for
   F and H style adjuster options, the valve may not open to relieve pressure.
