High Pressure, oleo-pneumatic, UHP cylinder valve - D354

D354 valve with oleo-pneumatic actuator is designed for keeping the highest level of purity of the gas. No particle are generated thanks to its tight diaphragm technology. Commonly used for UHP, 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
