Product description of single plate check valve:
H74H, H74W, H74X single-plate check valve is an ultra-thin check valve with short structure size and single disc design. Compared with the traditional swing check valve, this series of valves has no external leakage, Can be installed in any position, good sealing performance, low linear vibration, low pressure drop and zero seat ring wear advantages.
The working principle of single plate check valve:
The single-plate check valve is a disc type ultra-thin check valve. The disc is attached with an O-ring seal, which has good sealing performance, and is assisted by a spring to close, and the action is sensitive. It is especially suitable for places with limited installation space. It has the advantages of simple structure, beautiful appearance, light weight and convenient installation. It is mainly suitable for water supply system, petroleum, chemical industry, metallurgy and other industrial sectors. It is most suitable for places with limited installation space.
Product features of single plate check valve:
1. The structure is very short in length, small in size and light in weight, which brings great convenience to the installation, handling and storage of pipes for the valve, and can save a lot of materials and reduce costs.
2. The valve is an integral structure, simple and compact, the impact force is small when the valve is closed, the water hammer pressure is small, the valve life is long, and the reliability is high.
3. It can be installed horizontally or vertically, and it is light in weight, and it is not necessary to set a support for the valve.
4. The flow channel is smooth, the fluid resistance is small, and the valve disc can be fully opened under a small pressure difference.
