VARIVENT® Mixproof Valves Type R are used for mixproof separation of incompatible media at flow path intersections. In the closed position of the valve (non-actuated position) always two seals are located between the two pipes. Due to its radial arrangement of the seals, the valve is switching leakage-free. 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. The valve is equipped with a balancer. The balancer prevents that the valve disk is forced open in case of pressure hammers produced in the pipe system.
