Product description

The functions of the explosion-proof electric ball valve in the work have been greatly improved, and such ball valve can be widely used in petroleum, chemical industry, water treatment, paper making, power stations, heating, light industry and other industries.

Product features
1.The body is made of hard aluminum alloy with great resistance to corrosion and its IP grade is IP67;
2.Fully enclosed squirrel-cage motor has small size, large torque and small inertia. The insulation grade is F, and built-in thermal protection switch is equipped to avoid damaging the motor;
3.Hand wheel design ensures safety and reliability and it is featured by labor saving and small size
4.Dryer can prevent the moisture in the actuator from coagulating and keep the internal electrical components dry;
5.Mechanical and electronic double limit switch
6.It can provide overload protection to avoid damaging the motor
7.Precise double worm and gear mechanism with efficient transmission, large torque, high efficiency and low noise is adopted to prevent inversion, and the transmission part is stable and reliable and refueling is not necessary.
