RX04 UHP DIAPHRAGM VALVE

The RX04 Ultra High Purity (UHP) diaphragm valve was formely Model M4SI.

Our RX04 UHP Diaphragm Valves (or ultra-high purity diaphragm valves) are critical pressure control devices utilised in many clean applications by industries including semiconductor, food & beverage, pharmaceutical & medical and high-tech research & development. This latest addition to the Rotarex UHP product line is the first of it's kind threadless and springless design diaphragm valves for the highest level of purity.

Our selection of Rotarex UHP diaphragm valves are all assembled, tested and packaged in Class ISO 4 cleanrooms as well as individually serialised for full traceability, giving you the confidence and control you need over your high purity systems. The RX04 valve has low, medium and high pressure versions, as well as various actuation types including multi-turn handwheel, quarter-turn handwheel and pneumatically actuated.

These valves can also be made available with open-close indicator (on multi-turn handwheel version) and are suitable for panel mounting.

RX04 Key Features:

• 100% Helium Leak Tested for optimal safety
• Assembling, testing and packaging in Class ISO 4 cleanroom

• 270° multi-turn handhweel with open-close indicator
• Lock Out Tag Out (LOTO) option available

There is no compromising when it comes to ultra-high purity gases – you will need a regulator that will suffice reducing the pressure on a UHP line safely and effectively. UHP gases are used a lot in manufacturing processes, from LEDs and photovoltaics to semiconductors, and diaphragm valves must meet different requirements depending on the application.

Our partner Rotarex is one of the world's leading gas control equipment manufacturers. When companies worldwide need products that enable new technologies and systems, they turn to Rotarex. And it’s been that way since the first Ceodeux valves won innovation awards in the 1920’s, propelling them into the top tier of cylinder valve manufacturers. Rotarex never stopped inventing, designing, prototyping and manufacturing first-of-a-kind products that solve industry challenges and invent new, safer ways of working. We can offer a broad range of cylinder valves, high purity pressure regulators, diaphragm and line valves, supply/switchover boards and UHP fittings & cylinder connectors. Rotarex specialise in ultra-high purity gas, food processing, medical gas, cryogenic/LNG, fire suppression, automotive and many more applications.
