Product Detail

Product Description

Wafer ultra-thin check valve is a disc type ultra-thin check valve. It adopts 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. It is mainly suitable for water supply system, petroleum, chemical industry, metallurgy and other industrial sectors, and it is more suitable for places with limited installation space.



Product Features

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.
