Manual SS Butterfly Valves (KF flanged)

Fit rough, bypass, and forelines that require high conductance, low profile, rapid opening, and throttling action.

Features

  • Manually actuated (pneumatic and motorized available on request)
  • Remove easily from the line for servicing
  • High vacuum valves rotate open to give a high gas conductance path
  • Recommended in operating conditions involving frequent changing and cleaning; recommended for applications not requiring line of sight or mechanical movement through the bore
  • Temperature Range: -10° C to 80° C (approx.)
