The RTZ1-50/0.4(0.8)E(K)Q Series Gas Pressure Regulator is a high-performance interconnected pressure regulation system designed for precision and safety. Featuring a sophisticated geared lever structure, this series is engineered to provide stable pressure regulation for various medium and low-pressure non-corrosive gases, ensuring consistent flow and operational reliability in demanding industrial environments.
Built to exceed rigorous production standards (GB 27790—2020), these regulators integrate a built-in overpressure safety cut-off and a safety relief device. This comprehensive safety architecture eliminates the need for additional external safety valves, significantly reducing installation complexity and operational costs while maintaining maximum protection for the pipe network.
