DI Ball check valve adopts Alu coated with rubber ball as its disc that rolls up and down in the valve port in the effect of fluids, achieving the valve open and close. Its sealing is very good, and even it is silent close without water hammer. Slide ball type check valve adopts full bore design, which makes it have big flow, small resistance, small head loss that is 50% smaller than that of swing type check valve.
Ball type check valve can be mounted vertically or horizontally on the pipeline of cool water, hot water, industrial and domestic sewage system. Slide ball type check valve is more applicable to submersible sewage pump. Prosper Flow can design and manufacture the ball type check valve according to BS5153 with sizes of 2”~12” (DN50~DN300mm).

How does a di ball check valve work?

A ball check valve has an internal conically tapered shape for the sealing seat and a ball. ... It forces the ball off of the sealing seat and allows media to flow through. When there is back pressure, it moves the ball back to the seat seal (assisted by the spring if designed with one).
