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
The standard ball is designed with a NBR rubber lined metal core, and the rubber hardness is optimized to prevent the ball from getting stuck in the seat. Balls of polyurethane are suitable for abrasive media and when different balls weights are needed to prevent noise and water hammer. A full and smooth bore ensures full flow with low pressure loss and eliminates the risk of deposits at the bottom that could prevent tight closure.
