The MEDENUS gas pressure regulator type R51 ensures a constant outlet pressure - regardless of the primary (inlet) pressure - when the gas usage varies and ensures a quick pressure regulation when the flow rate abruptly changes. The gas pressure regulator R51 is best used for smaller flow rates or e.g. for ignition gas trains. The gas pressure regulator R51 is suitable for gases in accordance with DVGW Code of Practice G260/262 and all other neutral and non-corrosive gases (others upon request).The gas pressure regulator R51 is available only with flange connections DN25, a maximum inlet pressure of 16 bar and a maximum outlet pressure of 3 bar. All gas pressure regulators are certified by DVGW and CE.
