QF-CR series gas safety valves are designed to monitor the gas-side pressure of accumulators, provide protection against overpressure, and enable controlled gas discharge when necessary. The product combines charging, discharging, and test gas pressure functions into a single valve mechanism to support the safe operation of the accumulator.

With its durable steel or stainless-steel body and leak-proof design, it ensures safe operation in high-pressure hydraulic systems. It offers long service life, rapid response capability, and ease of maintenance.
