Ultra-thin check valve
Product overview
Structural characteristics
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 the pipe layout of the valve, and can save a lot of materials and reduce the cost.
2, the valve is the whole structure, simple and compact, small impact force when the valve is closed, small water hammer pressure, long valve life, high reliability.
3, can be installed horizontally or vertically, light weight, do not need to set support for the valve.
4, the flow path is smooth, the fluid resistance is small, the valve disc can be fully opened under a small pressure difference.
