EDF valve

The innovative springless check valve for clean applications.

 

Maximum hygiene with no maintenance required. Tightness guaranteed in all installation positions, even vertical with downward flow.

The patented YGROS technology sets new standards in the plant engineering world, thanks to its magnetic principle that replaces the function of the traditional spring.

Suitable for fluids and steam.

Resistant up to 220°C.

The ultimate solution for applications in pharmaceutical, chemical, cosmetic, food, beverage, CIP/SIP industries.

BENEFITS AT A GLANCE

  • Maximum hygiene : Only the shutter comes into contact with the product. There are no springs, discs or other components which could contaminate it, this means no contamination and no stagnation point
  • Safe closing: ensured by patented magnetic principle
  • Any installation position possible: it can be installed in horizontal, vertical up and down positions.
  • Energy saving: its innovative working principle and design allow for a smooth flow, minimising pressure drop.
  • Laminar flow: No turbulence
  • Maintenance free
  • Longer valve life: thanks to high chemical resistance of the materials
