Wear-proof actuation mechanism Patent pending

Revolutionary frictionless actuation mechanism and adjustable sealing force valve technology

What makes our GC and HPLC valves frictionless is a unique, proprietary technology that allows the force profile to release pressure during actuation. The innovation resides in a unique actuator that slightly reduces the force applied on the insert prior to rotation. 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.


  • 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
