Valve WAFER

The innovative Wafer valve, specially designed for applications in vacuum, gas and water treatment industries.

Maintenance-free. Tightness guaranteed in all installation positions, even vertical with downward flow.

WAFER check valve resists up to 220°C for fluid gases and steam.

BENEFITS AT A GLANCE

  • Assenza di vibrazioni: this innovative design principle is particularly advantageous for systems in which the fluid is compressible (gas) or is handled at low pressure. Ygros WAFER valve is kept open with a minimal pressure difference.
  • High chemical thanks to its design in 1.4404 (AISI 316 L) and 1.4462 (Duplex), it guarantees a longer valve life construction.
  • Safe closing: ensured by its patented magnetic principle.
  • Any installation position possible: it can be installed in horizontal, vertical up and down positions.
  • Energy saving: its operating principle and innovative design allow a smooth and free flow (laminar flow), thus minimising turbulence and pressure losses.
  • Maintenance free
