Advancing gas chromatography and gas analysis

At CVProducts, innovation is built right into our DNA. So when we realized that existing technology just wasn’t good enough, we began challenging ourselves to develop better, smarter, more cost-effective gas analysis solutions. From products that use less gas to ones that require no spare parts, maintenance or consumables, everything we do is designed to improve efficiency and make things more simple for you – and more healthy for our planet.

Our technologies

Purge lip sealing valve (PLSV)

Our revolutionary disruptive analytic valve offers a longer lifetime than a diaphragm valve and the constant pressure drop of a conical rotary valve.

  • Purge technology eliminates inboard/outboard and cross-port leaks
  • Long lifetime: Over 1 million actuations
  • No change in pressure/flow drop across temperature range and life span
  • No dead volume effect

LipLOK fitting

With its two distinct levels of sealing, the LipLOK is patented technology that brings analytical performance and robustness together with better leak detection.

  • Sealing ring design offers better sealing integrity
  • No need for welding
  • Leak concentration chamber and septum for better leak detection
  • No dead volume effect

Wear-proof actuation mechanism

This proprietary technology allows the force profile to release pressure during actuation, reducing insert wear and increasing its lifetime.

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