Working principle and purpose of the product:

The electrical signal device of the fire signal butterfly valve is designed with a worm and worm gear drive device at the top, which is directly connected to the valve stem for transmission. In the precision fully enclosed electromechanical device, there is a mechanical indicator for valve opening degree, imported electrical components, and rust proof parts. The output signal is stable and reliable for a long time.

Signal butterfly valves are suitable for controlling valves in fire protection systems. In situations where constant opening is required, when the valve is opened or closed to a designated position, the signal device on the valve can send a signal to the fire detection center to display whether the butterfly valve is open or closed, in order to prevent the valve from accidentally closing and affecting the automatic sprinkler fire extinguishing function.
