Description:

Introducing our revolutionary backflow preventer – a game-changing solution for protecting your water supply from potential contamination risks. With their advanced design and innovative features, our backflow preventers ensure a continuous, uninterrupted supply of clean, safe water to your residential or commercial space.

The main function of a backflow preventer is to stop the backflow of water and prevent any contaminants or contaminants from entering the main water line. It acts as a barrier, protecting your drinking water from potential hazards such as chemicals, bacteria, or other contaminants that could back up into the pipes. Our backflow preventers are a reliable and essential device that maintains water supply purity and ensures the health and safety of your family, employees or customers.

Our products feature a dual-check backflow prevention valve for an extra layer of protection. These valves work together to provide a double barrier against backflow. If one valve fails, another valve activates, maintaining the integrity of the system. Each valve is carefully designed and extensively tested to meet industry standards and regulations. Made from high-quality materials, our backflow preventers are durable and long-lasting, ensuring years of worry-free operation.

Installation is simple and easy and can be easily integrated into new or existing piping systems. Our backflow preventers are designed to be low maintenance, reducing the need for frequent service or repairs. Its compact and stylish design ensures minimal space requirements, making it suitable for both indoor and outdoor installations.

Characteristics:

1. It is of compact and short structure; slight resistance; water-saving (no abnormal drain phenomenon at the normal water supply pressure fluctuation); safe (in abnormal loss of pressure in the upstream pressure water supply system, the drain valve can be open timely, emptying, and the middle cavity of backflow preventer always takes precedence over the upstream in air partition); on-line detection and maintenance etc. Under normal work in economic flow rate, water damage of product designis 1.8~ 2.5 m.

2. Two levels check valve’ s wide valve cavity flow design is of small flow resistance, rapidly on-off seals of check valve, which can effectively prevent damages to the valve and pipe by sudden high back pressure, with mute function, effectively extending the service life of the valve.

3. Accurate design of drain valve, drain pressure can adjust the pressure fluctuation value of cut off water supply system, to avoid the interference of the system pressure fluctuations. On-off safely and reliably, no abnormal water leakage.

4. Large diaphragm control cavity design makes the reliability of the key parts is better than that of other backlow preventer, safely and reliably on-off for drain valve.

5. The combined structure of large diameter drain opening and diversion channel, complementary intake and drainage in the valve cavity have no drainage problems, completely limit the possibility of back down stream and siphon flow reversals occur.

6. Humanized design can be online test and maintenance.

Applications:

It can be used in harmful pollution and light pollution,for toxic pollution,it is also used if it cann’t prevent backflow by air isolation;
It can be used in source of branch pipe in harmful pollution and continuous pressure flow,and not used in preventing backlow of
toxic pollution.
