Manual Bellows Sealed SS Inline Valves (KF & ISO flanged)

Features

  • The moderate conductance of inline valves results from the gas flow making two right-angle turns through the valve.
  • Recommended for applications requiring a line-of-sight connection between two offset ports
  • Feature fluorocarbon o-ring seat seals, bellows-sealed shafts, and bonnet seals
  • Leak rate across seat: 2x10-9 mbar L/s
  • Pressure Max: Atmospheric pressure
  • Pressure Min: 1x10-9 Torr
  • Normal repairs can be made without removing the valve body from the system
  • Available in manual or pneumatic actuation

NOTE: Pneumatic valves require a solenoid operator (sold separately). Please see the Inline Valve Accessories chart for the sizes/voltages that are available.
