Features of IRV10-26 Relief Valve Pilot-Operated Spool
1. Adjustments cannot be backed out of the valve.
2. Adjustments prohibit springs from going solid.
3. Hardened spool and cage for long life.
4. Optional spring ranges to 210 bar (3000 psi).
5. Fast, smooth response to pressure surges.
6. Industry common cavity.
 
Operation Symbol of IRV10-26 Relief Valve Pilot-Operated Spool
The IRV10-26 blocks flow from ① to ②until 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. The cartridge offers a fast response to load pressure changes in hydraulic circuits.     
NOTE: The IRV10-26 cannot be used in crossover relief applications.
