The DIN Ductile Iron Silent Nozzle Check Valve (PN10) is a high-efficiency non-return valve engineered to eliminate water hammer. Its streamlined "nozzle" internal geometry and spring-assisted disc ensure the valve closes before flow reversal occurs, protecting pumps and piping from shock. Built from robust Ductile Iron (GGG40/50) and rated for PN10, it features a short-stroke design for rapid, silent response in water distribution and HVAC systems.
