High Pressure, oleo-pneumatic, UHP cylinder valve - D354
D354 valve with oleo-pneumatic actuator is designed for keeping the highest level of gas purity. No particle are generated thanks to its tight diaphragm technology. Commonly used for ultra-high-purity, corrosive, reactive and toxic gases, its oleo-pneumatic actuator increase the seat closure force.
Key advantages
- Tied diaphragm design with minimal gas wetted volume
- Combined soft and metal seat design with low permeation rate
- Threaded weep hole for pipe away connections
- Strong closing force with the use of a hydraulic amplifier
