As a leading specialist in drive and control technology, Bosch Rexroth has a unique level of technological expertise. The Bosch Group is a leading global supplier of technology and services.

When pressure rises above the spring bias pressure, the poppet is lifted and flow allowed. The valve is closed (checked). Precision machining and hardening processes allow virtually leak-free performance in the checked condition.
