Inoxpa Double Seat Valve

The Inoxpa double seat valve is a pneumatic shut-off valve for hygienic applications.  The P-type valve (shown above) is part of the Innova range of seat valves specially designed by Inoxpa. 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). This enables the user to ensure that the leakage chamber can be cleaned by the independent lifting of the seats during the CIP cleaning of the line. Specific valve bodies for DIN and OD dimensions give improved drainability. The valve was designed using CFD ensuring optimal design. One of the benefits of this is the low maintenance aspect of the valve. The valve easily lifts out for maintenance by unbolting a clamp. See video below for more on this.
