INOXPA INNOVA D Tank Double Seal Mixproof Valve

for hygienic applications that require a safe and reliable separation between two distinct products. This valve is equipped with two seals that create a leakage chamber, maintained under atmospheric pressure, between the two seals. This unique design allows for a secure and contamination-free separation of two different substances, one of which is typically a cleaning medium, such as CIP (cleaning-in-place). This feature is particularly valuable in industries such as food, beverages, pharmaceuticals, and chemicals, where preventing cross-contamination during product changeovers or cleaning processes is critical.

To ensure leak prevention, compressed air is applied simultaneously to both the actuator and the leakage valves. This synchronized control guarantees that there is no risk of product or cleaning medium leakage through the leakage valve during the valve’s opening. When the valve is in the open position, the leakage valves remain closed, and when the valve is in the closed position, the leakage valves open, allowing any possible leaks to be safely channeled away. This intelligent design not only enhances safety but also protects the integrity of the products being processed.

Moreover, the leakage chamber can be easily cleaned through one of the two available leakage valves, ensuring that the valve remains hygienic and free of residues. This feature is particularly useful in processes where frequent cleaning and sterilization are necessary, ensuring that the valve performs optimally over time without compromising hygiene standards. The INNOVA D-type valve offers a highly efficient solution for managing product flow and separation in systems where safety, cleanliness, and product integrity are top priorities, providing long-lasting reliability and superior performance in demanding hygienic environments.
