CARILO 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 savings in 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 with API 598.
Features:
Light Weight, Versatile Design, and 80 to 90% lighter then conventional full body check valve.
Reduces pipe supports, simplifies piping, easier, less costly installation.
Spring Loaded double door design has low cracking pressure.
Disc open 80% to ensure positive closing
Materials and trims available for all services within temperature range.
Rubber To Metal or Metal To Metal Seat available
Neoprene, Buna-N, EPDM, Viton Silicon etc.
