The DI ball check valve adopts a streamlined full bore flow channel design, with no unnecessary protrusions to hinder fluid flow, and the loss is much lower than that of swing check valve and lift check valves, reducing about 50% compared to similar products.

In long-term operation, this ball type one way valve can reduce the energy consumption of the conveying pump, reduce pipeline operating costs, especially suitable for high flow, long-distance pipeline use, and balance high efficiency and energy conservation.

The ball type shutoff valve by relying on the dual effects of the gravity of the sphere and the reverse pressure of the medium, the sphere can quickly fall back to the valve seat, achieving instantaneous closure and avoiding water hammer impact caused by medium backflow.
