Technical Advantages NEOS double sealing shut-off valve

With its innovative design, the new VEOX mix proof double block and bleed valves, leak-free on opening, responds to the concerns and constraints of food processing. Its modular design enables it to be adapted to every precise case and cleaning constraint…

• Great resistance to expansion stresses and chemical products
• Supports overpressures under the plug with release to the leak chamber
• Instantaneous visualisation of any leaks  by the leak indicator
• The optimal cleanability  of the chamber and leak indicator with the valve closed thanks to cleaning indicator, as option
• Complete interchangeability of subassemblies
• Easy and quick maintenance thanks to clamp subassembly assembly

Specification of NEOS double sealing shut-off valve

Definox valves are favoured by many outstanding advantages such as:

– The intermediate plug ensures double protection, even during lifting of the banning plug.

– There is no danger of mixing between two different liquids.

Thanks to the patented design of the bottom plug, any transfer of CIP solution to the opposite side of the leak chamber is prevented.

Application of NEOS double sealing shut-off valve

With the above outstanding advantages, defines valves are very popular with investors in many fields such as:

– Food, pharmaceutical, chemical, and cosmetic industries

– Animal feed processing industry,…
