Flanged Water Check Valve DI Non Return Valve DN50-DN400

Ductile Iron Flanged End Ball Check Valve

1. PRODUCT PROFILE

A Ball Check Valve is a simple and reliable valve with the only moving part to block the reverse flow, is a spherical ball. The full-ported valve seat is uniquely designed allowing the ball to seat leak-tight without getting wedge into the valve seat. For vacuum or anti-flooding valve application, a "floating" rather than "sinking" ball is used. Due to its simple flow efficient and virtually maintenance-free design the valve is commonly specified and used in submersible wastewater lift stations.Prosper Flow can design and manufacture the ball type check valve according to BS5153 with sizes of 2”~12” (DN50~DN400mm).

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).
