Chemical, petrochemical, petroleum, paper, mining, electricity, liquefied petroleum gas, food, pharmaceutical, water supply and drainage, municipal, mechanical equipment, electronic industry, urban construction and other fields.
工作原理：
进口气动三片式内螺纹球阀当气动执行器与电路和系统气源接通后，空气通过管道A或B管进入A缸（B缸）推动活塞向一端运动，从而带动旋转轴和球芯转动90°。气动执行器顶部连动可视器，当绿色标志指向“开”字时标志阀门开启。回信器信号灯绿灯亮时阀门处在开启位置，而红灯亮时阀门处在关闭位置。配定位器可调节阀门管道流量。
Imported pneumatic three piece internal thread ball valve working principle:
Imported pneumatic three ball valve when the pneumatic actuator is connected to the circuit and system of gas supply, air enters the cylinder through the A pipeline A or B tube (B cylinder) to push the piston to the end of movement, so as to drive the rotary shaft and the ball core rotates 90 degrees. Pneumatic actuator linkage device when the top visible, green signs pointing to the "open" word mark valve open. When the green light is on, the valve is in the open position and the valve is in the closed position when the red light is on. With positioner can adjust the valve pipe flow.
