Cone Check Valve – Overview The check valve is a component that allows the flow in one direction only. The check valve design combines increased safety and efficiency with easy handling. Check valves 561 and 562 easily fit in all piping systems. The self-closing function and the silent operation of the valve support safety and comfort. Cone Check Valve – Features Safe, simple and efficient Type 561- 100 % leak-proof at a water column of 2 m Type 562 guarantees 100 % leak-tightness when the valve is in idle mode Gasket always in fixed position. Prevents slipping, bending or washing out Corrosion-resistant Autonomous self-closing mechanism without additional energy source Self-cleaning design – virtually no maintenance Optimised flow design Corrosion-resistant and high-pressure rating Wide range of materials for optimum chemical resistance Self-closing Valve permit a far higher flow rate than standard check valves with a ball
