德国TOP托普电动防爆球阀概述：
德国TOP托普电动防爆球阀有防爆电动执行器系列产品以及球阀组成，执行器采用一体化方案。以220V电源电压作动力进行开关调节，接受4-20mA电流信号或电压信号及单相电源即可控制运转。电动防爆球阀主要特点：不通电时，扳动离合器手柄可进行手动操作。通电时，离合器自动复位。
防爆球阀具有如下的一些优点：
流体阻力小，球阀是所有阀类中流体阻力zui小的一种开关迅速、方便，只要阀杆转动90°，球阀就完成了全开或全关动作，很容易实现快速启闭。密封性能好。球阀阀座密封圈一般采用聚四氟乙烯等弹性材料制造，易于保证密封，而且球阀的密封力随着介质压力的增加而增大。阀杆密封可靠。球阀启闭时阀杆只作旋转运动，因此阀杆的填料密封不易被破坏，而且阀杆倒密封的密封力随着介质压力的增加而增大。球阀的启闭只做90°转动，故容易实现自动化控制和远距离控制，球阀可配置气动装置、电动装置、液动装置、气液联动装置或电液联动装置。

The German TOP top explosion proof electric ball valve:
Germany TOP valve has a top electric explosion-proof explosion-proof electric actuator series products and ball valve, actuator with integrated scheme. 220V power supply voltage as power switch adjustment, 4-20mA current signal or voltage signal and single-phase power supply can control the operation. The main features of electric explosion-proof ball valve: when the power is not switched on, the clutch handle can be operated manually. When the power is on, the clutch is reset automatically.
Explosion proof ball valves have some of the following advantages:
Fluid resistance is small, ball valve is the smallest of all types of fluid resistance
Switch quickly and easily, as long as the valve rod to rotate 90 degrees, the ball valve is completed fully open or fully closed action, it is easy to achieve rapid opening and closing.
Good sealing performance. Ball valve seat ring is generally made of PTFE and other elastic materials, easy to ensure sealing, and the sealing force of the ball valve as the pressure increases with the increase.
Reliable stem seal. When the ball valve opens and closes, the valve stem is only rotated, so the packing seal of the valve stem is not easy to be damaged, and the sealing force of the valve stem sealing is increased with the increase of the medium pressure.
Valve opening and closing only 90 degrees rotation, it is easy to achieve automatic control and remote control, the ball valve can be equipped with pneumatic devices, electric devices, hydraulic devices, gas-liquid linkage or electro-hydraulic linkage device.
