H76x double disc butterfly check valve produced by our company is composed of valve body, disc, stem, spring and other parts. It is connected by clamp. Due to the short closing stroke of the valve disc and the spring loading, the water hammer phenomenon can be significantly reduced. The valve is mainly used in urban, industrial and high-rise building water supply and drainage pipe network. Because the length of its structure is shorter than the general check valve, it is most suitable for places with limited installation space.
