Threaded Cast Iron Check Valves

Threaded Ductile Iron Check Valve

Threaded Ductile Iron Check Valve

The threaded ductile iron check valve features a high-strength ductile iron body with threaded connections. The closure element is a rubber-coated ball; as flow progresses, the ball is pushed from its seat, and when flow stops, the ball returns to seal the line.

With a near-full bore flow path and no moving stem, it operates clog-free in fibrous, sludge and solid-particle fluids. Available in sizes 1″ to 2 1/2″, pressure class PN16; may be installed horizontally or vertically with upward flow.
