Valves handle applications in semiconductor and other processing, and are used most often to isolate pumps and sample entry locks from HV or UHV work chambers.

Features

  • CF Flanged (with Fluorocarbon O-Ring): Operate in the atmosphere to 10-9 torr pressure range, bakeable up to 150° C (in the open position)
  • General purpose Electropolished Stainless Steel
  • Vacuum brazed at 1,100° C to ensure reliable operation at HV and UHV pressures
  • Provide high conductance within a compact design
  • Shock-free operation with minimum vibration
  • 100,000-cycle service before requiring maintenance
  • Available in manual or pneumatic operation
  • Pneumatic valves close or remain closed in the event of power loss or loss of air pressure
  • All 1.5" flange O.D. and larger models incorporate magnetic REED switches for position indication
  • Pneumatic valves feature a 120VAC solenoid operator at no extra charge (other voltages, both AC and DC, available on request)
