The INNOVA S-type mix proof valve is a pneumatic shut-off double seat valve for hygienic applications. The leakage chamber, under atmospheric pressure, situated between the two seats ensures a safe interface between the two liquids, one of which is usually a CIP solution (cleaning agent).
The leakage chamber is cleaned via the CIP nozzle situated in the lantern.
