Handle Type Groove Signal Butterfly Valve

The XD381X groove signal butterfly valve is suitable for controlling valves in fire protection systems. When the valve is required to be normally open, 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, to prevent the valve from accidentally closing and affecting the automatic sprinkler fire extinguishing function. Product feature: XD381X groove signal butterfly valve is a centerline type butterfly valve developed by introducing foreign * * * technology. When the valve is mistakenly closed by 25% (1/4 of the full opening), the electrical signal device will output the signal of being mistakenly closed to the fire control center. The XD381X groove signal butterfly valve is a supporting product of the fire automatic sprinkler system. The electrical signal device of the XD381X groove signal butterfly valve is designed at the top of the worm gear and worm gear drive device, and is directly connected to the valve stem for transmission. In a precision fully enclosed electromechanical device, there is no mechanical indicator for valve opening, imported electrical components, and rust proof components. Output signal long-term * * *. It is a control valve for the ZS series automatic sprinkler fire extinguishing system in fire engineering. It is a butterfly valve with a worm gear transmission clamp and an opening and closing signal device, which has the function of displaying the opening and closing of the water source of the extinguishing device. The valve has good sealing performance, flexible opening and closing, accurate and reliable opening and closing display position, and moisture-proof characteristics.
