Product description

Worm gear fire-fighting groove butterfly valve has simple structure, small size and light weight, and consists of only a few parts. Moreover, it can be opened and closed quickly by rotating the hand wheel, the operation is simple, and it has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small, so it has better flow control characteristics.
