The nominal pressure and nominal diameter of the metal hard seal butterfly valve are the same. Which of the ordinary butterfly valve and gate valve is more tight?
The sealing performance of hard-sealed butterfly valves is much better than other ordinary valves, but there are many manufacturers, and the sealing performance of butterfly valves is also good. The pipeline valves in this column should be installed horizontally when installing, because the valve is very large and takes up The space is also relatively large, the electric hard seal valve is different, its volume is relatively small, and the space occupied is relatively small!
When choosing a valve, there are many issues to consider. The most important issue is to consider the temperature of the medium, the packing and sealing performance of the valve. It is stipulated that the nominal diameter of the valve cannot be greater than fifty. The elastic hard seal butterfly valve is our country. The new product, the high-performance hands-on hard-sealed butterfly valve adopts an eccentric and double eccentric sealing structure, which solves the shortcomings of the sealing surface sliding during the opening and closing process of the traditional method, and realizes the separation of the valve and the sealing surface when the valve is opened, reducing The friction of Shanghai, you can touch the sealing effect when it is closed!
