H76(H/X/Y)
Sandwich double disc check valve
The sandwich check valve is mainly composed of valve body, disc, stem and spring, and is connected by clamp. Due to the short disc closing stroke and spring loading, the water hammer phenomenon can be significantly reduced. Mainly used in municipal, industrial and high-rise building water supply, drainage pipe network, because its structural length is shorter than the general check valve, so easy to install
