The Raceway-Type Ball Check Valve utilizes a rubber-coated rolling ball as the valve disc. Under medium pressure, the ball rolls vertically along the valve body’s integrated slide rail to open or close the valve. This design ensures excellent sealing performance, silent closure, and eliminates water hammer. Optimized Flow Path: Features a streamlined inflow channel for high flow capacity and low resistance, with 50% lower head loss compared to swing check valves. Versatile Installation: Suitable for horizontal or vertical mounting. Applications: Ideal for cold water, hot water, industrial sewage, and domestic wastewater pipelines, particularly compatible with submersible sewage pumps. Pump Protection: Installed at pump outlets to prevent backflow and protect pumps from water hammer damage.
