The INNOVA T mixproof valve is a double seat pneumatic shut-off valve designed specifically for use in tanks and vats used for hygienic applications. A leak detection chamber under atmospheric pressure formed between both seats ensures that two different products are safely separated, one of which is usually CIP (cleaning agent).

The INNOVA T valve has two seats that form a leak detection chamber at atmosphere pressure for every type of operating condition. This means that any leaked product will enter the leak detection chamber before being discharged through the leak outlet. The leak detection chamber is closed when the valve is open, enabling the product to transfer from the tank to the pipes. This chamber is closed to the process when the valve is open, enabling the product to transfer from the tank to the pipes. Additionally, the valve can be cleaned to any level depending on the process.
