YEV CHECK VALVE

simplest springless check valve, suitable for food & beverage industrial plants.

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

YGROS patented technologysets new standards in the world of plant design, thanks to a patented magnetic principle replacing the conventional spring in Non Return Valves.
For food and beverage industry. Up to 150°C.


YEV valve is the simplest model of the entire Ygros range, but it does not lose its characteristics of Hygiene and reliability.

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

Benefits at a glance

  • Energy saving The innovative working principle and design allow for a smooth flow, minimising pressure drop
  • 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
  • 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
  • Laminar flow No turbulence
  • Maintenance free
  • Longer valve life Through high chemical resistance of the materials
