      1. The product is manufactured using advanced international production technologies, with high-precision testing equipment providing continuous monitoring throughout the process. It’s crafted on state-of-the-art CNC machining centers to ensure accuracy, while key components are imported from overseas to guarantee superior product quality.
      2. This product features a well-designed structure, with high-quality ductile iron and stainless steel materials ensuring a robust and long-lasting assembly. The main components are engineered for an impressive service life of up to 8 years.
      3. No professional installation required. The valve handwheel features clear "Fill" and "Drain" markings, making it easy for people of all ages to operate—simply turn the valve open to release water, and close it to prevent freezing. It’s incredibly simple to use!
      4. When freezing temperatures are expected during the cold winter months, simply operate the handle of this product to drain all water from outdoor pipes above ground level, ensuring complete freeze protection. This effectively solves the common problem in cold regions where frozen and burst water pipes prevent access to tap water altogether.
      5. After the riser freeze-proof valve is installed, there’s no need to wrap it with any insulation material—simply turn on the water whenever needed, and it’ll stay frost-free instantly. This solution is not only elegant and high-end but also saves significant amounts of insulation material.

      1. Installation methods are divided into Type A installation (installed inside the inspection well) and Type B installation (directly buried).
      2. Before installing this product, please clean off any dust or foreign particles from the valve body and pipes.
      3. Depending on the local frost depth, connect the inlet of the lower valve body of the riser freeze-proof plug to the main water supply pipe below the frost line, following the direction indicated by the arrow. Ensure that at least 20 cm of drainage space is left beneath the outlet of the lower valve body (this space can be filled with pebbles or gravel to facilitate proper water drainage).
      4. Users can determine the height of h1 themselves based on their actual usage needs.
      5. It is recommended to install a main valve before the lower valve body of the freeze-proof plug for easier maintenance.
    [Installation Precautions]
      1) Before installation, the product should be stored in a cool, well-ventilated area. Avoid placing it in high-temperature, dry environments, direct sunlight, or areas prone to ozone generation.
      2) When installing, be sure to follow the direction indicated by the arrow on this product to determine the flow direction.
      3) Absolutely no use of this product in non-potable water pipelines.
      4) Before installing the product, confirm that water flows properly, stops flowing when turned off, and drains effectively. Follow the usage instructions for testing procedures. Under normal operation, water should flow smoothly when the faucet is turned on. During drainage, if you feel a slight suction sensation when placing your hand near the spout, that’s also normal.
      5) Except for maintenance, please do not disassemble, reassemble, or modify the product on your own, as this may lead to leaks or cause accidents.

Anti-freeze Valve Manufacturers _ How Tap Water Anti-freeze Valves Work

2022-08-03


Anti-freeze valve manufacturer—The municipal water anti-freeze valve features a built-in temperature-sensitive element that directly interacts with ambient temperatures, controlling the opening and closing mechanism between the piston and valve seat. When the ambient temperature drops below the set threshold, the thermal element contracts, pulling the piston downward to open the drain passage, allowing a small trickle of water to escape continuously. This steady flow prevents pipes from freezing. The municipal water anti-freeze valve operates autonomously via a temperature-sensing bulb, enabling self-powered opening and closing without the need for external energy, thus ensuring the stable operation of the water system.
