A slow closing check valve, also known as a slow closing check valve, is a valve used to prevent dielectric counterflow and eliminate destructive water hammers. It is usually installed in the water outlet of the pump, which can effectively reduce the water hammer pressure generated when the valve is closed, ensuring the safe operation of the pipeline network. The following is some introduction about the slow closing check valve in Chinese:
​
HH44X micro-retarding check valve is a valve for water supply and drainage pipelines, with light disc, large opening, significant energy saving effect, small fluid resistance, novel water hammer elimination mechanism design, stable and reliable sealing performance, good wear resistance, long service life, stable operation, no vibration and noise characteristics.
​
The 300X slow closing check valve is installed in the water supply system and other water supply pump outlet in high-rise buildings to prevent media backflow, water hammer and water hammer phenomenon of smart valves. The valve combines three functions of electric valve, check valve and water hammer eliminator, which can effectively improve the safety and reliability of the water supply system. In addition, it adopts the technical principle of slow opening, fast closing and slow closing to eliminate the water hammer and prevent the opening of the pump water hammer and the pump water hammer.
​
The slow closing check valve has the characteristics of light disc, wide opening, significant energy-saving effect, low fluid resistance, novel water hammer elimination mechanism design, stable and reliable sealing performance, good wear resistance, long service life and stable operation.
​
In terms of technical parameters, slow closing check valves have different sizes, such as DN40 to DN300, with different L, H, B sizes to adapt to different installation needs.
​
In addition, there are hydraulic control slow closing check valves, such valves operate automatically by hydraulic pressure, do not require other equipment and energy, easy to maintain, smooth opening, slow closing.
