BV-DS087 API/EN/CE/JIS/KS worm gear flange butterfly valve

          API/EN/CE/JIS/KS  worm gear  flange butterfly  valve                    

Description of flange butterfly valve:

Flange butterfly valve has simple structure, small volume, light weight, only by a few parts.And only need to rotate 90 ° can rapid opening and closing, simple operation, at the same time, the valve has good flow control characteristics.The butterfly valve butterfly plate installed on the diameter of the pipe direction.Cylindrical channels in butterfly valve body, disc disc around the axis of rotation, rotation Angle for 0 ° ~ 90 °, rotate to 90 °, the valve is fully open.Flange butterfly valve in the fully open position, the butterfly plate thickness is medium flows through the body when the only resistance, thus produced by the valve pressure drop is small, it has good flow control characteristics.Butterfly valves have a seal and metal seal two kinds of seal type.Elastic sealing valve, sealing ring can be embedded in the body or attached to the butterfly plate peripheral.
