Gas Flow Management

Gas Fittings - Valves - Regulators

An impressively large selection of harware for gas lines, from the gas source to the point of use!

Flow Metering and Control was one of our very first areas of technological focus; our involvement in mass flow control dates to 1989.

Today we propose an extensive range of gas management products for research labs and hi-tech production facilities. Included is a very complete family of tube fittings, pressure regulators and valves from the ROTAREX Group, a world-class leader in the field, with a global service infrastructure of 1200 employees across 10 factories (7 in the EU), 6 R&D centers, 23 sales centers and a network of distributors, including X-TRONIX AG serving CH & FL, to cover the globe.

The ROTAREX brand offers a broad range of valves, regulators, fittings and related equipment. It meets the requirements of every gas piping network and installation, offering a global gas component solution, from gas cylinder to the point of use.
