Ductile Iron Dual Plate Wafer Type Check Valve For Water Backflow Prevention
Product introduction:
Double disc check valves are used in pure pipelines, industrial, environmental protection, water treatment, and high-rise building drainage pipelines to prevent the reverse flow of media. The check valve adopts a clamp type, with two semicircles for the butterfly plate and a forced spring reset. The sealing surface can be made of wear-resistant material or lined with rubber for body welding, with a wide range of use and reliable sealing.
Double disc check valve consists of valve body, valve disc, valve rod, and spring parts etc. The check valve adopts wafer type, butterfly plate is two semicircular, and adopts spring forced reset, sealing surface can be body hard-facing wear-resistant material or rubber lining, wide range of use, reliable sealing.
The disc shutoff stroke is very short and under the effect of the spring, the valve can close quickly and prevent the big noise from water-hammering. It is widely used in water supply and drainage system, high-rise building and industrial park, because of its surface distance is short than other check valve, so it is more convenient for the confined space installation.
