High pressure cylinder and bundle valve with pneumatic actuator for corrosive gases - D131
Pneumatic cylinder Valve with Packed Needle Stem Design for High Purity Gas Applications
Key advantages
  • Freedom from seizure when used with corrosive gases- gas does not come into contact with the valve operating mechanism.
  • Positive and effective operation-valve spindle is mechanically linked to the operating hand wheel, which only requires low closing torque.
  • Long life-valve, all internal parts are replaceable
  • Adjustable gland packing-in the unlikely event of a leakage occurring past the valve spindle, when opening the valve, rectification is readily achieved by retightening the gland packing nut.
  • Low internal volume-this is particularly beneficial, when using the valve for hygroscopic, corrosive or high purity gases, where inert gas purging may be necessary before opening after closing the valve.
