DFH20/7 Mining intrinsic safety electric ball valveDetailed product description：

DFH20/7 mining intrinsically safe electric ball valve is mainly applicable to the automatic dust prevention, fire prevention and extinguishing automatic control spray with gas, coal dust explosion hazards, poor water quality and wide water pressure range in coal mines, as the automatic control switch of water circuit. This electric ball valve can be used independently or in conjunction with other monitoring systems. Electric ball valve is a new type of electric valve that opens and closes waterways by the rotation of a sphere. It has a wide range of water supply pressures, is not affected by sediment and sewage, has a large water supply diameter, short power on time during operation, and stable and reliable operation. It is an ideal water control valve with wide applications, long service life, high water transmission capacity, and strong anti-interference ability.
