CHECK VALVE EDF

The innovative springless non-return valve for sterile applications.
Maximum hygiene without any need for maintenance. Guaranteed tightness in all mounting positions (even vertically with downward flow)
The technology patented by YGROS sets new standards in the world of plant engineering, thanks to a magnetic principle that replaces the function of the spring. For fluids and steam. Resistant up to 220 ° C. The check valve is suitable for CIP / SIP. Finally a truly hygienic solution for applications in the pharmaceutical, chemical, cosmetic, food, beverage, etc …
  • No more springs that can break or jam.
  • No intermediate components to prevent flow.
  • No stagnation points.
  • No maintenance required.

BENEFITS

  • Maximum hygiene: Only the shutter comes into contact with the product. No stagnation points, no springs or other intermediate components that could contaminate it
  • Closing and sealing guarantee: Secured by the patented magnetic principle
  • Free positioning: Unlike other types of springless valves (such as ball valves), Ygros EDF retains its functionality on both horizontal and vertical installations.
  • Energy saving: Operating principle and innovative design allow a fluid and free passage, thus minimizing turbulence and pressure drops.
  • Laminar flow: Minimizes turbulence
  • It does not require maintenance
  • Long valve life: Thanks to the high chemical resistance of the construction materials used
