GF 562 valves feature a unique check cone element design that optimizes flow geometry and minimizes flow resistance and pressure loss. The check valve Type 562 (horizontal) closes absolutely leak-tight with the built-in spring, even in the de-energized state — without water column as well as in a horizontal position. The self-closing mechanism operates autonomously, without any other energy source, i.e. water column or flow. The streamlined check cone and the refined geometry in every detail provide for a significantly improved flow compared to valves with a check ball, without compromising functionality or leak-tightness. The effort involved in cleaning and servicing the valve has been reduced to a minimum due to the cone design, which offers the least possible contamination surface. With its sealing zone and the specially developed profile seal, the valve is absolutely leak-proof, even when closing very quickly.
