DCX3 DE double sealing shut-off valve - Definox

DCX3 DE double sealing shut-off valve are used in a wide variety of process and ancillary fluid applications, designed for efficient cleaning. The double sealing valve DCX3 DE can detect potential leaks between two isolated zones, thanks to an airlock system. It is an alternative to independent plug valves with a leakage chamber.

Technical Advantages DCX3 DE double sealing shut-off valve

With its innovative design, the new VEOX mixproof 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..

The DCX3 DE double sealing changeover valve performs the usual functions of a standard DCX3. It also enables a potential leak to be detected between the two isolated zones thanks to a chamber connected to the atmosphere.
This valve is an alternative to the mix proof leak chamber valves.

• PFA floating seal, perfectly cleanable, ensuring perfect leak-tightness at high temperature
• Spherical body with thick walls, different configurations possible: + T L
• Double non-mix proof plugs
• Leak chamber preventing any risk of mixing between lines
• Numerous connections possible: SMS, DIN, Clamp
• 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 clamping subassembly assembly

Specification of DCX3 DE 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 DCX3 DE 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,…
