The Medenus RS250 Gas Pressure Regulator and Shut-Off Valve guarantees a consistent outlet pressure, unaffected by fluctuations in the primary inlet pressure. This product excels in dynamic gas usage conditions, providing rapid pressure regulation during abrupt changes in flow rate. Furthermore, the integrated safety shut-off valve ensures secure operation by disabling the system if the pressure exceeds or falls below safe levels.

The Medenus RS250 Gas Pressure Regulator and Shut-Off Valve is compliant with the DVGW Code of Practice G260/262, making it suitable for a range of neutral and non-corrosive gases (additional gases available upon request). The Medenus RS250 features flange connections ranging from DN25 to DN100 and is capable of handling working pressures of up to 8 bar. All gas pressure regulators come certified by DVGW and CE, ensuring high-quality standards.

Our RS series regulators offer a variety of options, including a safety membrane, vent valve, remote release for the shut-off valve (SSV), noise reduction features, and more. For further information, please consult our documentation or contact us directly.
