HPLC Wear proof valve

It’s here! The first-ever wear-proof chromatographic valve

In the field of HPLC valves, there are many suppliers, but little differentiation. What’s more, for decades there’s been little or no innovation. We’re changing that with unique technologies designed for performance and durability. Based on our variable load mechanism that releases the sealing pressure during actuation, our new valve has an unprecedented lifetime.


  • Up to 5x longer lifetime than other valve technology
  • Better performance and quality
  • Variable sealing pressure technology
  • No dead volume


Wear-proof actuation mechanism Patent pending

Revolutionary frictionless actuation mechanism and adjustable sealing force valve technology

What makes our 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 we can use high pressure for sealing and a lower pressure 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
  • Ultra-high temperature model coming soon (+450° C)
  • Extra-long lifetime: lasts well over 2 million actuations
  • Smooth rotation, no gear-style CAM
