Product Description:
The non return valve is a hydraulic control combination device that strictly restricts the water in the pipeline to flow in one direction only when the backflow pollution of the tap water supply equipment, especially the drinking water pipeline is serious, and there is no effective device to prevent the backflow pollution. Its function is to prevent the backflow of the medium in the pipeline under any working conditions, so as to avoid backflow pollution. At present, the backflow preventer is mainly divided into two types: low-force backflow preventer and decompression type backflow preventer. According to the national standard, the head loss of the low-resistance non return valve is less than 3 meters, and the head loss of the decompression type non return valve is less than 7 meters.
1. The product has unique design, beautiful appearance, simple installation and convenient maintenance.
2. Double check and air partition to completely prevent backflow pollution under any working conditions
3. Accurate calculation, sophisticated processing, reliable performance and sensitive action.
4. Designed according to CJ/T 160-2002 standard
5. The inner and outer surfaces are sprayed with environmental protection coating to ensure the anti-corrosion and safety of the product
6. If the backflow preventer needs to be used in seawater, please specify when ordering
