Tied diaphragm cylinder valve for fluorine mixtures with pneumatic actuator

The D386S delivers the highest levels of purity and safety for typical applications using fluorine gas mixtures such as cleaning non-plasma deposition chambers and diffusion furnace for silicon-based films. Rotarex has designed the D386S cylinder valve with the challenges of fluorine nitrogen mixtures in mind. The new valve offers a wealth of specialized features to ensure the safety of operational staff and the purity of the F2/N2 mixtures to contribute to contamination-free manufacturing.

Key advantages

Pneumatic actuation
Valve is designed normally closed
The tapped vent hole allows the connection to a leak detector
Gas will not come in contact with the valve operating system
Backed up welded diaphragms provide a high leak tightness integrity up to 10-8 mbar.l/sec
Reduced dead spaces and gas wetted volumes allow easy purging process
No particle generating threads in the gas wetted part
Metal to Metal seat, fully suited for fluorine applications
