Product Description
2.5 Inch Ss 304 Pneumatic Double Seat Butterfly Valve (Type B)


Double seat butterfly valves can be used in food-processing, pharmacy and chemical industries. Leakage butterfly valve offers an easy and safe separation of products and prevents accidental mixing in case of gasket failure. The most usual applications are the ones that requires safe separation of the product and CIP solution in a single point ( not in manifolds), or at the end of a manifold( e.g CIP return) or entry of a CIP solution into a tank (through a spray ball).

Teh mixproof butterfly valve as a process element for the separation of medium is suitable for a variety of applications:
In CIP systems for separating CIP medium.
In flush-out processes
In water management
As pipe section shut-off valve for separating medium.
In CIP/gas management (breweries)
At storage tanks for separating product/CIP
As CIP return valve in a valve matrix.
Preferably suitable for liquid and gaseous medium without suspended matter/particles.

Operating principles:
It provides double safety: the two butterfly valves are simultaneously actuated by only one actuator. When the two valves are closed, there is a chamber between them. The chamber is under atmospheric pressure as it open to the exterior, thus, in case of failure of any of the two gaskets, leakage of the liquid product will indicate any possible mixing of products. The state of the gaskets is supervised by means of either fo the leakage detectors. The other detector (superior) controls the entry of the cleaning solution to prevent any kind of conmination in the chamber. These 2 leakage detectors provide optimal protection and enable cleaning of the intermediate chamber.
