ANSI Standard Stainless Steel Dual Plate Wafer Type Check Valve For
Corrosive Medium Use
Product introduction:
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.
