Structural characteristics of clamp type butterfly check valve

Check valves are installed in pipeline systems and their main function is to prevent medium backflow. Check valves are automatic valves that rely on medium pressure to open and close. In the past, H44 flange connected swing check valves and H41 flange connected lift check valves were commonly used in China. These traditional check valves are bulky, have high fluid resistance, high water hammer pressure when the valve is closed, difficult to install and maintain, and have a short service life.The main check valve product names of China Check Valve Network include:Butterfly Buffering Check Valve，Flange Tiny Drag Slow Close Muffler Check Valve，Flange Tiny Drag Slow Close Butterfly Type Check Valve，Two-plate Tiny Drag Slow Close Butterfly Check Valve，Energy-saving Muffler Check Valve

In response to the problems of traditional structure check valves, based on the American API standards and German DIN standards, and combined with China's rich experience in valve testing, research, development, design, and manufacturing over the years, we have developed the H76 double disc swing check valve and H71 double disc lift check valve series products. After years of use by enterprises and equipment manufacturers in industries such as petrochemicals, metallurgy, electricity, light industry, and food, they have achieved good results and received high praise from users.

Structural features:

1. The structural length is short, only 1/4 to 1/8 of that of traditional flange check valves;

2. Small in size and light in weight, its weight is only 1/4 to 1/20 of traditional flange check valves;

3. The valve disc closes quickly and the water hammer pressure is low;

4. Both horizontal and vertical pipelines can be used for easy installation;

5. Smooth flow channels and low fluid resistance;

6. Sensitive action and good sealing performance;

7. Short valve disc stroke and low impact force when closing the valve;

8. Overall structure, simple and compact, beautiful appearance;

9. Long service life and high reliability.
