Flanged Ball Check Valves
Flanged Swing Check Valve
A flanged swing check valve with a rubber-coated ball as the closure element and ductile iron body. The ball is pushed to the side chamber by flow; when flow stops, the ball returns to its seat and blocks reverse flow. Without shaft and hinge, it operates without clogging in fibrous, muddy and solid-laden wastewater.
Supplied in ductile iron GGG50 body from DN50 to DN150. Horizontal or upward-flow vertical installation is possible; the cover can be opened for easy ball inspection.
