Seat valve with leak detection The INNOVA type D is a single-seat shut-off valve with two seals, a leak chamber is formed between the seals, in which atmospheric pressure is maintained. This valve allows you to control the flow of two different products, one of which is usually CIP, without the risk of mixing them.
Compressed air is supplied simultaneously to the actuator and to two auxiliary leakage valves in order to prevent leakage at the time of valve opening. The valve is open - the leak valves are closed /the valve is closed - the leak valves are open.
The chamber is washed through one of the leak valves.
