Medenus manufacture a comprehensive range of gas pressure regulators, gas filters and gas safety shut off valves. They are 100% German manufactured and can deliver quickly. Flowstar is their authorised UK agent. Gas pressure regulators serve to ensure a constant outlet pressure, regardless of the inlet pressure or when the gas usage varies and the flowrate abruptly changes. Gas safety shut-off valves automatically interrupt the gas flow when there is an excess pressure or gas shortage. Gas filters are mainly used in gas pressure regulating and measuring stations to protect equipment.
