Double disc valves They are widely used in the processes of the food, cosmetic, pharmaceutical and chemical industries. The LBV (Leakage Butterfly Valve) provides simple and reliable separation of products and prevents accidental mixing in case of gasket failure. These valves are most often used in those processes where reliable separation of the product and CIP solutions is required at one point (not in manifolds), or at the end of the manifold (for example, CIP return) or at the inlet of the CIP solution into the container (through the washing head).
The principle of operation
Valve LBV provides double protection: the two discs are simultaneously powered by a single drive.
When the shutters are closed, a camera is formed between them. The chamber is open, therefore it is under atmospheric pressure, and in case of gasket failure, leakage of liquid product will indicate possible mixing of products. The condition of the gasket is monitored by one of two leak detectors.
