Fire Control Signal Butterfly Valve

Product introduction:

BUTTERFLY valve is a throttling device, suitable for high-rise building fire protection system and other need to show the valve switch status on the pipeline system.

Signal butterfly valve is suitable for petroleum, chemical industry, food, medicine, paper-making, water and electricity, ships, water supply and drainage, smelting, energy and other system pipeline. It can be used as regulating and throttling equipment on a variety of corrosive and non-corrosive gas, liquid, semi-fluid and solid powder lines and containers.

Signal butterfly valve is equipped with a signal device, which can send out electrical signals to show the opening and state of the butterfly plate, it is an important component of automatic sprinkler system, normally it is installed at both ends of the alarm valve group or at the entrance of each branch pipe of the system. When the alarm valve set or pipe network is being repaired, turn it off, using worm gear drive shaft and butterfly plate rotation to realize opening and closing and control flow. By rotating the hand-wheel of worm gear and worm drive device, the butterfly plate can achieve the purpose of opening and closing and regulating the flow, and the hand-wheel rotates clockwise to close the valve. A micro switch is arranged in the transmission box, which can output the closing and opening signals of the valve and show the different positions of the butterfly plate.

Product technical paramters:

Product features:

1, small and light, easy to disassemble and maintenance, and can be installed in any position.

2, simple structure, compact, 90° rotating open and close quickly.

3, the operation torque is small, labor saving and lightweight.

4, to achieve complete sealing, gas test leakage is zero.

5, Different parts material to be suitable for a variety of media.

6, flow characteristics tend to straight line, good regulation performance.

7, opening and closing test times up to ten thousand times, long service life.

8, where the use of gate valve, check valve (ball stop valve) "> globe valve, plug valve, hose valve and diaphragm valve pipeline, especially in high-rise building fire system and need to show the valve switch status of the pipeline system, can be replaced by the valve.
