Ductile Cast Iron 300X Slow Closing Check Valve

What is slow closing check valve

Slow closing check valve is widely used in high-rise buildings, living areas and other water supply network systems and urban water supply projects. It can not only prevent media backflow, but also its slow opening and closing design makes the valve more stable in the opening and closing process, reduces the impact on the system, and effectively improves the safety and reliability of the water supply system. In addition, the appearance of the epoxy powder coating, has a good anti-corrosion effect.

300X Slow Closing Check Valve Features:

  1. Excellent Material: It is made of ductile cast iron, which possesses high strength, high toughness, corrosion resistance, and wear resistance, ensuring the stable performance of the valve even in harsh working environments.
  2. Slow Closing Function: This valve is designed with a slow-closing mechanism that gradually slows down the closing speed during the closing process, preventing the occurrence of water hammer and protecting the pipelines and equipment from impact and damage.
  3. Excellent Sealing Performance: High-quality sealing materials are used between the valve disc and the valve seat to ensure good sealing performance of the valve in the closed state, preventing medium leakage.
  4. Lightweight Operation: The valve adopts a reasonable structural design and is made of high-quality materials, making the opening and closing operations of the valve lightweight and flexible, reducing the labor intensity of operators.
  5. Easy Installation and Maintenance: The valve adopts standard flange connections, facilitating installation and disassembly. At the same time, the internal structure of the valve is simple and clear, easy to maintain and inspect.
