What is the electric butterfly valve? Please, great God!
The output signal is stable and reliable for a long time. The valve has an electric node, which is drawn out to the control center by signal line, and the signal line voltage is 12V. In fact, the valve is open and closed, there is a signal to the consumer control center, easy to monitor, the valve in addition to the electric node, with the ordinary valve is not much difference, there are also signal butterfly valve.
Therefore, this butterfly valve is the best matching product of automatic fire sprinkler system. The structure characteristics and working principle: the top design electrical device the butterfly valve of the worm and the worm gear driving device, and with the stem straight connecting transmission. In the closed precision electromechanical device, opening mechanical instructions and imported electrical components and parts with rust proof valve.
ZSDF type fire signal butterfly valve uses: top of the ZSDF type fire signal butterfly valve with the valve opening and closing signal device, when the valve is closed by 25% (open degree 4/1), the signal device output signal was mistakenly closed to the fire control center.
