Overview

Description

RV10-20X is a screw in, cartridge style, direct acting, poppet type, hydraulic relief valve intended for use as a pressure limiting device for common hydraulic circuit protection. It is intended for use in mineral based or synthetic (with lubricating properties) hydraulic fluids

Operation

The RV10-20X blocks flow from port 1 to 2 until sufficient pressure is present at port 1 to force the poppet from its seat. The cartridge offers fast response to load changes in typical hydraulic circuits requiring low internal leakage

note: grv10-20 not recommended for crossover applications
