WAFER Valve

The innovative wafer valve developed for vacuum, gas, and water treatment industry applications.

Smart and versatile solution engineered for vacuum, gas, and water treatment systems. Suitable for installation in horizontal, vertical upward, and vertical downward positions. For fluids, gases and steam.

Applications:

Gas|

Water Treatment

Resistant up to 150 or 220°C

No more springs that can break or misfire

No flow obstruction components

No stagnation points

No chatter

This innovative design principle is especially advantageous for systems handling compressible fluids (gases) or operating at low pressure. The YGROS WAFER remains open with a minimal pressure differential.

High chemical resistance / longer valve life

Due to the 1.4404 (AISI 1.4404 (AISI 316 L) e 1.4462 (Duplex).

Safe closing

Ensured by patented magnetic principle.

Any installation position

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.

No periodic maintenance required

Full traceability for all metal components and seals.
