Product Details

Product description

The fire signal flange butterfly valve is an important component of the automatic sprinkler system. The worm gear drives the shaft and the butterfly plate to rotate to realize the opening and closing and control the flow. By rotating the hand wheel of the worm gear transmission device, the butterfly plate is opened and closed and the purpose of adjusting the flow rate is achieved. The hand wheel rotates clockwise to close the valve. There is a micro switch in the box of the transmission device, which can output the closing and opening signals of the valve and display the different positions of the butterfly plate.
