IRV10-26 Pilot-Operated Spool Relief Valve

IRV10-26 pilot operated unloading valve

The IRV10-26 Relief Valve Pilot-Operated Spool is a high-performance valve designed to protect hydraulic systems from excessive pressure. It features a pilot-operated spool mechanism that enables precise pressure regulation and rapid response to pressure changes. Its robust construction and reliable operation make it an essential component for maintaining system safety and preventing damage.

Features of IRV10-26 Relief Valve Pilot-Operated Spool

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.
