RELIEF VALVE

Overview

Description

The RV10-21X is a screw-in, cartridge style, hydraulic relief valve for use as a pressure limiter.

Operation

The RV10-21X allows flow passage from port 1 to port 2, while normally blocking oil flow in the opposite direction. the cartridge has a fully guided spool which is spring-biased closed until sufficient pressure is applied at port 1 to open to port 2.
