EDF Valve

The innovative springless check valve for hygienic applications.

Maximum hygiene without the need for maintenance. Guaranteed tightness in all installation positions, including vertical with downward flow. The patented YGROS technology sets new standards in process engineering, thanks to its magnetic principle that replaces the function of the traditional spring. Suitable for both fluids and gases.

Applications:

Beverage|

Chemical|

Cosmetic|

Food|

Pharmaceutical

Resistant up to 150 or 220°C

No more springs that can break or misfire

No flow obstruction components

No stagnation points

EDF Eccentric Valve

Eccentric self-draining version available. Suitable for horizontal installations.

Maximum Hygiene

Only the shutter comes into contact with the product. There are no springs, discs or other components which could contaminate it, this means no contamination and no stagnation point.

Safe closing

Ensured by patented magnetic principle.

Any installation position

It can be installed in horizontal, vertical up and down positions.

Energy saving

Its innovative working principle and design allow for a smooth flow, minimising pressure drop.

Laminar flow

No turbulence.

No periodic maintenance required

Long valve life

Thanks to high chemical resistance of the materials.

Full traceability for all metal components and seals.
