EDF 3-A
YGROS 3-A CHECK VALVE
The 3-A authorized springless check valve
The innovative springless check valve.
Specially engineered for the US market, officially approved by the 3-A institute.
Fully hygienic design. Maintenance free. Suitable for horizontal, vertical up and down installation (even in vertical pipes with flow down).
YGROS patented technology sets new standards in the world of plant design, thanks to a patented magnetic principle replacing the conventional spring in Non Return Valves.
For fluids and steam. This non return valve is suitable for CIP/SIP. Up to 220°C.
Finally a really smart solution for your clean applications in the dairy, beverage, food, pharmaceutical, cosmetic and chemical industry.
- No more springs that can break or misfiree.
- No flow obstructing components.
- No stagnation point, no media entrapment.
- Maintenance free.
Benefits at a glance
- Maximum hygiene (spring free design): Only the shutter comes into contact with the product. There are no springs, discs or other components, which means no contamination and no stagnation point.
- Safe closing: Provided by integral magnets.
- Any installation position possible: Unlike other springless check valves, an YGROS Valve can be installed in the horizontal, vertical up and down positions.
- Energy saving: The innovative working principle and design allow for a smooth flow, minimising pressure drop.
- Laminar flow: No turbulence
- Maintenance free
- Longer valve life: through high chemical resistance of the materials
