Jan 5, 2017 -- With the rapid development of modern science and technology, the pace of industrial development is also beyond the expectations of many people, especially in the development of high-tech industry. Not only the industry has been significantly improved, their corresponding industry momentum is very good. Butterfly double sanitary check valves are among the products that benefited from this industry boom. But I believe many users are not very familiar with butterfly double check valves, so let’s take a quick look at some of the major structural characteristics of them:

1. The valve flap closes quickly, the water hammer pressure is small.
2. Both horizontal and vertical pipes can be used, easy to install.
3. The flow channel is smooth, the fluid resistance is small.
4. Agile movement, good sealing performance.
5. The valve flap distance is short, the impact force of closing the valve is small.
6. Integrated structure, simple and compact, beautiful appearance.
7. Long service life, highly reliable.
8. The structural length is short. It’s only about one-fourth to one-eighth of that of traditional flange check valves.
9. Small size, light weight. The weight is only about one-fourth to one-twentieth of that of traditional flange check valves.
