CHAODA Valves Group is specialized in manufacturing Wafer Check valve(Ranges from Class150 To Class900, PN10 To PN160) with following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc. Wafer check valve consists of Valve body, disc, stem, spring and etc with wafer type connection ends. Wafer type check valve could obviously reduce the happening of water hammer with its quick closing together with the structure of spring loaded. As the Face to face dimension of Wafer Check valve is smaller than other types of check valve, it's very suitable to act as the device to prevent the backflow of medium in pipelines served in the Water supply &Â drainage system of urban, industry and top buildings, environmental protect area, water treatment and etc.

Application of excavator hydraulic cylinder:
The hydraulic cylinder of an excavator is an important component, mainly used to control the movement of the excavator's mechanical arm, stick, bucket head, and other parts. Specific application scenarios include:
1. Construction engineering: Excavator hydraulic cylinders can be used for excavation and transportation of earthwork, excavation of foundation pits, road construction, pipeline laying, and other construction projects.
2. Mining: Excavator hydraulic cylinders can be used for ore mining, blasting, transportation, and loading in mining.
3. Agricultural production: excavator hydraulic cylinder can be used for Land consolidation, irrigation and drainage, ditch excavation, crop harvesting and other work in agricultural production.
4. Hydraulic engineering: Excavator hydraulic cylinders can be used for river dredging, embankment construction, reservoir construction, and other work in hydraulic engineering.
5. Garbage treatment: The excavator hydraulic cylinder can be used for garbage cleaning, compression, transportation, and landfill in garbage treatment.
In summary, excavator hydraulic cylinders are widely used in various engineering and production fields, and are important tools for improving work efficiency and production efficiency.
