Zoloto Dual Plate Check Valve, Size 2 - 5 inch, Connection Form Flange, Material Cast Iron

Key characteristics design industry-standard api 594. Wafer type design, To take lesser space than the conventional check valve. Being easy is more, To carry rigid than the standard check valve with a swing mechanism valve, Which needs expensive foundation and special supports. Being stresses are, Cylindrical body uniformly distributed. Much longer seat life because of bronze / s. S to rubber contact. Less wear and tear of seat surfaces. End connections are intended to suit flanges drilled to ansi b class, 125 / asme b class, 150. Water hammering effect is minimized in since the, This design closing of valve does not depend upon any back pressure or flow. Each plate being half of the measurements of the swing check valve disc, Provides straight flow path offering minimal resistance as a result of the spring s assistance as closing of the valve initiates right when flow velocity dips below the designated minimum velocity.
