The D389 series is a pneumatically operated, tied diaphragm double seal type cylinder valve for high flow UHP corrosive gases.
This cylinder valve is primarily designed for UHP, corrosive, reactive and toxic gases and is responsible for keeping the highest level of purity of the gas. The seat closure force is increased thanks to its oleo-pneumatic actuator. The tight diaphragm technology allows no particle are generation in the gas wetted parts.
Rotarex Puretec manufactures and provides ultra high purity cylinder valves for technical & inert gases, reactive gases, corrosive gases and toxic gases. The Puretec division carries out production in their ISO4 certified cleanroom with 100% helium leak testing on all of the products. Each valve undergoes strict quality control procedures including more than 14 visual, tactile or microscope controls on each valve, microscope toroid controls before and after the valve mounting, and internal/external tightness tests registered into the traceability system.
Tied diaphragm seal valve technology is often favoured by electronics manufacturers and chemical applications. Some of the unique advantages to this technology include:
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.
