Shuttle check valve VARIVENT® Y series

Mixproof Shuttle Valves Type Y series VARIVENT® are used for diverting liquids in a pipe system, i.e. from one pipe on to two pipes, with mixproof separation between the central and the upper pipe. In the closed position of the valve (non-actuated position) always two seals are located between the two pipes (shut off between central housing and upper housing). If one of the seals fails, leakage may directly drain to the open via the therefore provided leakage outlet of the valve without intermixing with the product being in the second pipe. For shut-off between the central and the lower valve housing, only one seal is used. The VARIVENT® Mixproof Shuttle Valve has been tested and approved by the Dairy Institut in Kiel, Germany. Mixproof Shuttle Valves, type Y meet the 3A standard. Application: Heaters Tank systems
