Tri-Clamp Double Hinge Stainless Steel Clamp

The Medenus RS255 Gas Pressure Regulator and Shut Off Valve guarantees a consistent outlet pressure, irrespective of the primary inlet pressure. This device adeptly manages variations in gas usage, providing rapid pressure regulation when there are sudden changes in flow rate. Additionally, the integrated safety shut off valve ensures secure operation by shutting off in the event of excessively high or low pressure levels.

The Medenus RS255 Gas Pressure Regulator and Shut Off Valve complies with DVGW Code of Practice G260/262 and is suitable for all neutral and non-corrosive gases (other gases available upon request). It comes with flange connections ranging from DN50 to DN100 and is capable of handling working pressures up to 16 bar. All gas pressure regulators in this range are certified by DVGW and carry CE certification.

Every regulator in the RS series boasts several options, including a safety membrane, vent valve, remote release for the shut off valve (SSV), noise reduction features, and more. For comprehensive details, please consult our documentation or reach out to our team.

The FSSCDF Forward Acting Rupture Discs feature precision micro-scored sections that open in controlled petals, using four, six, or more radial score lines to ensure a clean, reliable opening while minimising the risk of petal separation. This design makes them particularly well suited for high burst pressure applications and for systems operating under cycling or pulsating conditions with gases or liquids, without compromising safety margins.

These discs respond to overpressure within milliseconds, opening fully without fragmentation, and are ideal for protecting safety relief valves. They support an operating-to-burst pressure ratio of up to 85%, offer excellent corrosion resistance, and can be further enhanced with an optional PTFE lining. In many applications, the discs can also withstand full vacuum conditions without additional supports, providing flexible installation options.
