YSV CHECK VALVE

The innovative Extractable and Springless non return Valve

Fully hygienic design. Maintenance free.
Suitable for horizontal, vertical up and down installation (even in vertical pipes with flow down).

Finally the first extractable springless check valve, which can be quickly removed from the plant, without removing flanges or pipes and other components.

YGROS patented technology sets new standards in the world of plant design, thanks to a patented magnetic principle replacing the conventional spring in Non Return Valves.

  •  No more springs that can break or misfire.
  •  No flow obstructing components.
  •  No stagnation point, no media entrapment.
  •  Maintenance free.

Benefits at a glance

  • Maximum hygiene (spring free design) Only the shutter comes into contact with the product. There are no springs, discs or other components, which means no contamination and no stagnation point
  • Extractable Valve without intervening on the plant
  • Safe closing Provided by integral magnets
  • Any installation position possible Unlike other springless check valves, an YGROS Valve can be installed in the horizontal, vertical up and down positions.
  • Energy saving The innovative working principle and design allow for a smooth flow, minimising pressure drop.
  • Laminar flow No turbulence
  • Maintenance free
  • Longer valve life Through high chemical resistance of the materials
