Product Features and Advantages
Noise reduction function: Through special designs such as streamlined channels and buffer devices, it can effectively reduce the water flow impact noise generated when the valve opens and closes, and minimize the noise pollution during system operation.
Check performance: It can automatically detect the direction of water flow. When backflow occurs, the valve closes quickly to prevent the medium from flowing backward, protecting the equipment and components in the pipeline system from damage caused by backflow impact.
Good sealing property: High-quality sealing materials and advanced sealing structures are adopted to ensure that the valve can achieve reliable sealing under different working pressures and temperatures, avoiding medium leakage and ensuring the normal operation of the system.
Low resistance characteristics: The internal flow channel of the valve is reasonably designed to minimize the obstruction to the water flow, allowing the water to pass through smoothly, reducing the head loss, and improving the operating efficiency of the system.
Durability: It is usually made of corrosion-resistant and wear-resistant materials, such as stainless steel, bronze, etc. It can withstand long-term water flow scouring and various working conditions, has a long service life, and reduces the frequency of maintenance and replacement.
