Product overview
Clamp ultra-thin check valve is a disc type ultra-thin check valve, using 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, small linear vibration, small pressure drop and zero seat wear advantages. It is mainly suitable for water supply systems, petroleum, chemical, metallurgical and other industrial sectors, and is more suitable for places with installation space restrictions.
Structural features
1. The structure length is very short, the size is small and the weight is light, which brings great convenience to the installation of valves, handling, and storage pipelines, and can save a lot of materials and reduce costs.
2. The valve is the overall structure, simple and compact, small impact force when the valve is closed, small water hammer pressure, long valve life and high reliability.
3. It can be installed horizontally or vertically, with light weight, and there is no need to set up supports 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.
