HRV09-P0
HRV09-P0
A screw-in, cartridge-style, direct-acting, poppet-type hydraulic relief valve, the HRV09-P0 is designed for use as a pressure limiting device in hydraulic circuits that require fast response and low hysteresis.
Operation
The valve blocks flow from port ① to ② until the pressure at ① is sufficient to move the spring-opposed poppet from its seat, allowing for quick adaptation to load changes.
