GF 561 valves feature a unique check cone element design that optimizes flow geometry and minimizes flow resistance and pressure loss. The self-closing mechanism operates autonomously with minimal line pressure. 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.
