WAFER CHECK VALVE

The one and only springless WAFER check valve
The innovative springless wafer valve developed for applications in the vacuum, gas and water treatment industries
It does not require maintenance. Guaranteed tightness in all mounting positions (even vertically with downward flow). The WAFER check valve resists up to 220 ° C.
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 flickering.
  • No stagnation points.
  • No maintenance required.

BENEFITS

  • Absence of vibrations and flickering: this innovative principle is particularly advantageous in systems where the fluid is compressible (such as gases) or is treated at low pressures; in fact the Ygros WAFER valve remains open with a minimum pressure difference.
  • Chemical resistance: thanks to the construction in 1.4404 (AISI 316 L) and 1.4462 (Duplex), which also guarantees a longer life of the valve
  • Closure and sealing guarantee: ensured by the patented magnetic principle.
  • Free positioning: Ygros WAFER maintains its functionality both on horizontal and vertical installations.
  • Energy saving (laminar flow): operating principle and innovative design allow a fluid and free passage, thus minimizing turbulence and pressure drops
  • It does not require maintenance
