Oleo-pneumatic UHP cylinder valve for highly oxidizing gases – D356
The D356 UHP cylinder valve with oleo-pneumatic actuator is designed for Ultra High Purity highly oxidizing and reactive gases, ensuring the highest level of gas purity thanks to its tied diaphragm technology. Its oleo-pneumatic actuator increases the seat closure force for maximum safety.
Key advantages
- Tied diaphragm design with minimal gas wetted volume
- Metal to metal sealing
- Patented operation mechanism
- Threaded weep hole for pipe away connection
- Strong closing force with the use of a hydraulic amplifier
