CHECK VALVE YSV

The innovative springless removable non-return valve
Maximum hygiene without any need for maintenance. Guaranteed tightness in all mounting positions (even vertically with downward flow).
Finally , the first removable springless check valve , which can be removed from the system quickly, without removing the flanges, pipes and other components.
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.
  • No more springs that can break or jam.
  • No intermediate parts that could impede the 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.
  • Removable valve without intervening on the system.
  • Closing and sealing guarantee Secured by the patented magnetic principle.
  • Free positioning Unlike other types of valves without, Ygros YSV 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.
