Dual Plate Check Valve

Fangwen Dual Plate Wafer Check Valve has One Piece cast heavy stronger Body configuration provides reduced weight and size compare to a swing check valve or lift check valve. This results in saving Initial cost, space and pipe support element installation.

The Dual Plate, Wafer Check Valve employs two-spring-loaded plates hinged on a central hinge pin. When the flow decreases, the plates close by the action of torsion spring before flow reversal takes place. All features put together make the Dual Plate Check Valve as the most efficient & versatile design. It is also referred to as SILENT CHECK VALVE

It is much easier to install between standard gaskets and line flanges, and therefore is more cost effective to install and to maintain.

Its design complies with API 594 and API 6D, testing to API 598.

Flange Dual Plate Check Valve

Fangwen Valves has been a manufacture in manufacturing Dual Plate Check Valves with a global supply footprint. We have been supplying special face-to-face dimensions for Dual Plate Check Valves in Double Flanged construction for the smaller-sized valve where it is not possible to accommodate two flanges within API 594 dimensions for these sizes and ratings. This addresses all concerns / reservations of some customers / end users about using Wafer / Wafer-Lugged configurations in process lines.

Fangwen Flange Dual Plate Check Valve s designed and manufactured strictly to International Standards API 6D, API 594, ASME B16.34 or Equivalent,
