How it works

A vacuum valve assembly used to isolate or route gas/vacuum paths in semiconductor equipment.

Valve type, port geometry, actuator style, seal condition, and flange size must match the tool vacuum plumbing.

Technical guide
bellows valve

Uses a bellows-sealed mechanism to reduce leakage and particle generation.

pneumatic actuator

Uses air pressure to open or close the valve.

KF/NW
Quick-flange vacuum fitting size family; KF40 and NW40 are commonly treated as equivalent nominal sizes.
SS
Stainless steel when supported by listing text.
What to verify before purchase
  • Exact revision and part-number suffix on the physical label
  • Connector, flange, mounting, or interface compatibility with the target tool
  • Actual condition, completeness, included accessories, and calibration/leak-test status where applicable
Confirm with the seller
  • Exact OEM datasheet specifications
  • Guaranteed machine compatibility beyond listed evidence
  • Condition or calibration status unless supplied by the seller
