Three years before a global player in silicon valley was founded, Dieter Medenus already recognized the possibility of producing gas pressure regulators in his own residence to meet a worldwide demand. Within a few years, Dieter Medenus earned an international reputation due to his high quality level. MEDENUS grew into a brand - the company grew in the same way. Until the retirement of Mr. Medenus in 2004, he perfected the high quality standard of the regulators. Regulator quality remains our top priority. We create a wide range of controllers for worldwide use by combining high-quality materials...

GAS PRESSURE REGULATION FOR HYDROGEN UP TO 16 BAR BY USING ALUMINIUM ALLOYS Owing to the increasing importance of the topic regarding gas pressure regulation of hydrogen and contradictory statements regarding the use of aluminum alloys for these applications up to 16 bar, we, as MEDENUS Gas-Druckregeltechnik GmbH, have commissioned a comprehensive investigation and literature search by the university RWTH Aachen concerning this issue. The objective was to examine, first and foremost, the Aliuminium alloys used by MEDENUS Gas-Druckregeltechnik, with the aim to investigate the open questions scientifically...

QUESTION The hypoeutectic aluminium cast alloy AlSi7Mg0.3 (EN-AC 42100) is being used widely in the automotive industry or aviation and aerospace technologies and is also being used for safetyrelevant structural components. This range of applications is due to the favourable properties of the material, such as low density, good casting properties, good mechanical properties in the heat-treated state, and generally good corrosion resistance. Previously, steel casting, cast iron, and brass materials have been used as material for gas pressure regulation fittings for hydrogen. However, due to the...

R 50 | GAS PRESSURE REGULATOR FOR SIMPLE APPLICATIONS WITH STABLE INPUT PRESSURE (± 5%) DESIGN AND FUNCTION The gas pressure regulator R 50 has the function of keeping the outlet pressure of a regulation section downstream of a gas pressure regulator constant within specified limits. The gas flows through the actuator housing in the direction of the arrow. The internal measurement line port is used for passing the outlet pressure to be regulated to the bottom of the diaphragm comparator of the diaphragm assembly. It compares the actual value with the command variable preset by the force of the...

R 51 | GAS PRESSURE REGULATOR DESIGN AND FUNCTION The gas pressure regulator R 51 has the function of keeping the outlet pressure of a regulation section downstream of a gas pressure regulator constant within specified limits, independently of changes in the gas tap or inlet pressure. The regulator is composed of the actuator housing and “diaphragm assembly plus actuator” functional unit. The valve seat model is pre-pressure-compensated. The gas flows through the actuator housing in the direction of the arrow. The internal or external measurement line port is used for passing the outlet pressure...
