A patented diaphragm check valve, which maintains a bubble-tight seal in whatever position it is mounted, is being launched by Plast-O-Matic Valves Inc., of Cedar Grove, N.J. Because they are not dependent upon gravity, mounting position or reverse flow, the valves represent a significant advancement and improvement over conventional ball type check valves. The outstanding feature of this valve is a patented diaphragm, which automatically positions itself against the valve seat in an identical location every time.
