LYV® Double Flanged Dual Plate Check Valve Introduction
Model series: H76, H77, H71, H72, H74, H46, the passage is: DN15~1200mm, 1/2"~84" pressure: 1.0Mpa~42Mpa, 150Lb~2500Lb, the temperature is -196~540℃, the material is cast iron, carbon steel, stainless steel (304, 316, 316L), biphase steel, chromium molybdenum steel, brass and other materials. Widely used in power, water, heating, chemical, chemical fertilizer, oil refining, metallurgy, paper, medicine, wine, construction and other industries.
Clamping check valve,D71W clamping check valve is composed of body, disc, stem and spring and other parts, using clamping connection. Water hammer can be significantly reduced due to short disc closing travel and spring loading. The valve is mainly suitable for urban, industrial and high-rise buildings water supply, drainage pipe network. Because its length is shorter than other check valves, it is suitable for places with limited installation space.
For clamp check valve, butterfly check valve for pure pipeline and industrial, environmental protection, water treatment, high-rise building water supply and drainage pipeline, to prevent the reverse flow of the medium

LYV® Double Flanged Dual Plate Check Valve Feature And Application
1, small size, light weight, compact structure, easy maintenance
2. The valve plate adopts dual type, which can be closed by itself under the elastic force of the spring
3, because of the speed closing effect, can prevent the backflow of the medium
4, the valve body structure length size is small, good rigidity
5, safe and convenient, can be used for horizontal and vertical installation
Implement standard for sandwich check valves
1. Flange connection size: GB/T1724.1-98
2, Structure length: GB/T12221-1989, ISO5752-82
