Wear-proof actuation mechanism

What makes our GC and HPLC valves so unique is that they use a revolutionary, frictionless actuation mechanism – a proprietary technology that allows the force profile to release pressure during actuation. The result is that high pressure can be used for sealing and a lower pressure can be used during rotation, reducing the insert’s wear and increasing its lifetime.

Key features:

  • Field-adjustable sealing force allows valve to be tuned for each application, avoiding excessive sealing force
  • Extra-long lifetime: lasts well over 2 million actuations
  • Smooth rotation, no gear-style CAM
