Cast Iron Dual Plate Wafer Type Check Valves, PN 16 (Art - 1082)
Design standard API 594.
Wafer Type Design, to take lesser space than the
conventional Check Valves.
Being light in weight, is more rigid than the standard
Swing Type Check Valves, which needs expensive foundation and special supports.
Being cylindrical body, stresses are uniformly
distributed.
Much longer seat life because of Bronze / S.S to Rubber
contact.
Less wear and tear of seat surfaces.
End connections are designed to suit flanges drilled to
ANSI B Class-125 / ASME B Class-150.
Water hammering effect is minimized in this design, since
the closing of valve does not depend upon any back pressure or flow.
Each plate being half of the size of the swing check
valve disc, provides straight flow path offering minimal resistance because of the spring’s
assistance as closing of the valve initiates as soon as flow velocity dips below the
designated minimum velocity.
