Product introduction

D371F46 Butterfly valve is suitable for use in -50℃～150℃ various concentrations of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids, strong oxidizing agents, FEP is also suitable for various concentrations of strong alkali organic solvents, and other corrosive gases, liquids and other media on the pipeline.

Product characteristics

D371F46 Butterfly Valve is used to realize the opening, closing and adjustment of the valve by using the butterfly plate rotating together with the valve stem as the opening and closing parts. Butterfly valve in the pipeline in addition to cut off and cut off the flow with, in recent years has been the sealing performance as the evaluation of the main indicators, favored by the market. In addition, the butterfly valve also has the advantages of small size, light weight, simple structure, compared with the same parameters of the gate valve, the average weight reduction of 30 ~ 50%, the butterfly plate can be rotated 90 degrees to realize the opening and closing process, but also due to the rotary axis on both sides of the butterfly plate by the medium force is approximately equal to the torque is reversed, so that some of the opening and closing torque is small.

Driving method

Electric fluorine lined butterfly valve, pneumatic fluorine lined butterfly valve, worm gear fluorine lined butterfly valve, manual fluorine lined butterfly valve.
