TVI Ball Check Valves (6" - 10")

Design Specifications

Ball is of solid thermoplastic material in 6" size and in 10" size the screen is PVDF. The Body has full length ribs for maximum flow, minimum pressure drop, and to eliminate ball sticking and chatter. Seat is full circle and resilient. A molded gasket seal and seat enlarges seating surface and facilitates maintenance. Valves require less than one (1) PSI to open and 3 -5 PSI to close drop tight. Valves are capable of installation in either vertical or horizontal pipe run. Valves become foot valves by attaching a screen assembly.
