The liquid passes through the flexible hose housed inside the casing that acts as support and actuator.
The hose provides sealing and separates the product from the valve casing.
The air is injected into the casing, it compresses the hose and cuts the flow of the product.
The air pressure, required to keep the valve closed, is between 1 and 2 bar higher than the product pressure inside the hose.
Pneumatically operated NO valve.
Full bore design, no pressure losses.
Easy cleaning.
Easy replacement of the hose.
Robust construction.
Optimum sealing for product with solids, fibers, etc.

The flexible hose valve is a pneumatically actuated full bore valve.
It presents the best solution for the transfer of liquids with solids in suspension, fibers, etc. that might be trapped blocking the valve in case another valve type is used.
It is widely used in applications requiring the delicate treatment of the product and minimum turbulences.
