Cast Iron Dual Plate Wafer Type Check Valve, PN 16
Salient Features
Design standard API 594.
Wafer Type Design, to take lesser
space than the conventional Check Valve.
Being light in weight is more rigid than the standard Swing
Type Check Valve, 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.
The water hammering effect is minimized in this design
since the closing of the valve does not depend upon any back
pressure or flow.
Each plate being half of the size of the swing check valve disc
provides a straight flow path offering minimal resistance
because of the spring’s assistance as the closing of the valve
initiates as soon as flow velocity dips below the designated
minimum velocity.
