Manual Bellows Sealed SS Angle Valves (KF flanged)

Reliable, economical, general-purpose components for HV and UHV applications requiring cleanliness and corrosion resistance.

In the open position

  • Edge-welded bellows and valve seat move out of the gas path thereby achieving high conductance

Features

  • Leak rate across seat: 2x10-9 mbar L/s
  • Pressure Max: Atmospheric pressure
  • Pressure Min: 1x10-9 Torr
  • Feature fluorocarbon o-ring seat seals, bellows-sealed shafts, and bonnet seals (select copper for higher temperature bakeout and better ultimate vacuum)
  • Available in manual or pneumatic actuation
  • Normal repairs can be made without removing the valve body from the system

NOTE: We list a wide variety of standard tube sizes from 3/8" to 4". Other sizes and valves with mixed flanges are available on request.

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