The clamping double-flap check valve is an automatic valve, which is mainly used to prevent the backflow of the medium and ensure the one-way flow of the medium in the pipeline.
### How it works
The working principle of the double-flap check valve depends on the internal disc structure. When the medium flows in the forward direction, the pressure of the medium pushes the disc to open, allowing the medium to pass through the valve. When the medium stops flowing or backflows, the disc automatically closes under its own gravity and the action of the backflow medium, thus preventing the backflow of the medium.
### Features
1. **Compact structure**: The double-valve clamp-on check valve adopts short structural size, compact design, and occupies small space, which is suitable for places with limited installation space.
2. **Good sealing performance**: O-ring is usually attached to the valve disc, which can provide good sealing performance and effectively prevent media leakage.
3. **Sensitive action**: Due to the short closing stroke of the disc and the spring loading, the disc can be opened and closed quickly under a small pressure difference, and the action is sensitive.
4. **Low water hammer pressure**: The quick closing feature of the double-flap clamp check valve significantly reduces water hammer and protects the piping system.
5. **Small linear vibration**: When working, the vibration of the valve is small, which helps to prolong the service life of the valve.
6. **Convenient maintenance**: The structure of the valve is simple, the disassembly and maintenance are more convenient, and the maintenance cost and use cost are reduced.
### Apps
Double-valve clamp check valves are widely used in water supply and drainage pipe networks of urban, industrial and high-rise buildings. Its main functions include preventing the backflow of the medium, preventing the pump and drive motor from reversing, and the release of the medium in the container to ensure that the pressure in the container is stable.
### Tech Specs
- **Nominal DN**:D N250
- Nominal pressure:P N16
- **Applicable medium**: water, steam, oil, sewage, acid and alkali
- **Applicable temperature**: Stainless steel body is used for acid medium -29°C~200°C.
