The XD371X-10 and XD371X-16 clamp type 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 closing incorrectly and affecting the automatic sprinkler fire extinguishing function.
