INNOVA D Double Seal Mixproof Valve

Home / Products  / Valves and fittingsSeat valves /  Double Seal Mixproof Valve INNOVA D

The INNOVA D-type valve is a pneumatic shut-off single seat valve with two seals that, by means of a leakage chamber under atmospheric pressure formed between the two seals, enables a safe separation of two different products, one of which is usually CIP (cleaning medium).


Compressed air is simultaneously applied to the actuator and to the leakage valves to prevent leakage through the leakage valve when the valve opens. Valve open - leakage valves closed / valve closed - leakage valves open.

The leakage chamber can be cleaned through one of the two available leakage valves.
