KF valves

KF components Features

• The typical KF or NW assembly consists of two identical flanges, a center-ring, and an aluminum clamp with a wingnut fastener frequently connect and disconnect without tools.
• The vacuum seal is effected by uniform application of pressure by the clamp on 15^o surface of the flange.
• The mating flange surfaces compress an O’ring (held in place by metal centering ring) to generate a seal.
