Features:
The D371F46 wafer type fluorine-lined butterfly valve uses the butterfly plate that rotates with the valve stem as the opening and closing part to realize the opening, closing and adjustment of the valve. In addition to cutting off and shutting off the flow of the butterfly valve in the pipeline, in recent years, the sealing performance has been regarded as the main indicator for evaluation, which is favored by the market. In addition, the butterfly valve has the advantages of small size, light weight and simple structure. Compared with the gate valve with the same parameters, the average weight is reduced by 30~50%. The opening and closing process can be realized by rotating the butterfly plate by 90 degrees. The force of the disc is approximately equal to the medium, and the torque is opposite, so the opening and closing torque is small.
According to the driving method, it can be divided into: Electric fluorine-lined butterfly valve , pneumatic fluorine-lined butterfly valve , worm gear fluorine-lined butterfly valve , manual fluorine-lined butterfly valve
