wafer type check valve

wafer type check valve

Wafer type check valve employs 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 wafer type check valves as the most efficient and versatile design.

Wafer type check valve has distinct advantages over conventional swing check valves. Stronger, lighter and smaller size. This results savings in initial cost, space and pipe support element installation. It weights about 1/8yh weight of conventional valve. Structurally sound hydraulically engineered. Flexible installation can be installed in horizontal or in vertical line without any special pipe support. The light weight and short face-to-face dimension of valve makes it easy to install between standard gaskets and line flanges. Besides, wafer type check valve mainly consists of the body, seat, disc, pin and other necessary fittings. The valve body can be manufactured from the cast iron and ductile iron. And the disc can be made of the monel, ductile iron, Al-bronze, ductile iron etc. The stainless steel is widely applied to manufacuture the other components.

Moreover, the wafer type check valves widely finds its applications in various sectors, such as vapours, air-conditioning, water-supply, cooling installations, steam, condensate systems, oil pipelines and natural gas line.
