How it works

A vacuum valve assembly used to open, close, or isolate a vacuum line or chamber port.

Correct valve style, flange size, actuator type, and seal condition are important for vacuum integrity, conductance, and tool safety interlocks.

Technical guide
vacuum_isolation

Vacuum valves isolate chambers, pumps, and gas-handling sections so maintenance or process steps can occur without exposing the full system.

KF40
A small-flange vacuum fitting size; exact flange compatibility should be verified from the installed valve and mating hardware.
What to verify before purchase
  • Verify the exact MDC model stamping because KAV-150-P, KAV-150-P-10, and KIV-style wording appear in the evidence.
  • Confirm KF40 interface, actuator configuration, seal condition, and pneumatic port requirements.
Confirm with the seller
  • Exact MDC suffix and rebuild status are not confirmed.

Product reference only. Confirm fitment, revision, included components, and specifications before purchase.
