Hover to ZoomEDF VALVOLA
The EDF (External Drainable Flush) valve is a bottom-mounted hygienic valve designed for direct installation on process tanks. Its compact, angled body ensures complete drainability and minimizes dead space, making it ideal for sterile and clean-in-place (CIP/SIP) applications in pharmaceutical, biotech, food, and cosmetics industries.

- 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 possible : 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.
- Maintenance-free : No need for regular servicing.
- Longer valve life : thanks to high chemical resistance of the materials.
