Cylinder pressure regulator, 200 bar, CO2/argon, 0 - 25 bar - Riegler 146759

Cylinder pressure regulator, Flange pressure 200bar, for non-flammable gases, Gas type: Carbon diox./argon, Work. press. 0-25,0bar Single-stage type in pressed brass version in accordance with DIN EN ISO 2503, with shut-off valve and safety valve as well as pressure gauge each for cylinder content and working pressure. Bottle pressure reducers are used to reduce a gas that has been compressed, liquefied and dissolved in a bottle at a certain filling pressure/upstream pressure to a much lower, as constant as possible back pressure/overpressure, as independently as possible of fluctuations in the upstream pressure and flow rate. Cylinder pressure reducers with connection to gas cylinders are suitable for reducing the pressure of various gases. They have a type approval in accordance with DIN EN ISO 2503 for welding, cutting and related processes. The connections are designed in accordance with DIN 477.

About Cylinder pressure regulators

A cylinder pressure regulator takes the high filling pressure of a gas cylinder and passes on an adjustable, constant working pressure to the torch or device behind it. Regulation starts at 0 bar, and depending on the version the upper end lies between 1.5 and 25 bar. Two gauges show cylinder content and set working pressure separately.

What matters when choosing

• Gas type and cylinder connection come first. The group covers oxygen, compressed air, nitrogen, carbon dioxide/argon, argon/helium and combustible gas, and each gas has its own cylinder connection.
• Maximum working pressure defines the model. End values start at 1.5 bar for fine control and reach 25 bar where the consumer needs more pressure.
• Outlet threads are G 1/4 male, G 1/4 female and the left-hand versions G 1/4 LH female and G 3/8 LH female. Check which hand of thread the connected fitting requires.
• Material governs load capacity and weight. Pressed brass and brass carry the pressure, steel in black or brass finish is used for housing parts, PA and PA 66 for the light versions.
• Sealing materials are listed as NBR, EPDM and FKM, chosen according to the gas passing through the regulator.

Typical applications

• Oxy-fuel welding and flame cutting, where fuel gas and oxygen are regulated separately.
• Shielded arc welding with carbon dioxide/argon or argon/helium.
• Purging and leak testing of pipework with nitrogen.
• Mobile compressed air supply from a cylinder where no network is available.
• Test benches and laboratory stations drawing a gas at constant pressure.

The regulators are single-stage designs to DIN EN ISO 2503 and come with a shut-off valve and a safety valve. The 46 articles in this group are produced in Italy, Poland, the Czech Republic, Germany and China.
