What is Butterfly Valve?
The butterfly valve is a valve that uses a disc-type opening and closing member to reciprocate about 90° to open, close or adjust the medium flow. The butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, easy and fast to operate, but also has good flow regulation and closing and sealing characteristics at the same time. When the butterfly valve is fully opened, Has a small flow resistance.
When the opening is between about 15° and 70°, it can carry out sensitive flow control. Therefore, the application of butterfly valves is very common in the field of large-diameter adjustment.
