The integral mining explosion-proof electric flange gate valve is suitable for flammable and explosive occasions, with high safety factor, strong operating function, and stable performance. There are two types of explosion-proof products, dI and dIIBT4. dI is suitable for non mining working faces in coal mines; DIIBT4 is used in factories and is suitable for explosive gas mixtures in IIA and IIB level T1 to T4 environments. The performance of the integral mining explosion-proof electric flange gate valve meets the requirements of JB/T8528-1997<Technical Conditions for Electric Devices of Ordinary Valves>. The performance of the explosion-proof type meets the requirements of GB3836.1-2000<General Requirements for Explosion proof Electrical Equipment for Explosive Environments>and JB/T8529-1997<Technical Conditions for Explosion proof Valve Electric Devices>. And it has been verified by the National Explosion proof Electrical Product Testing Center and obtained an explosion-proof certificate.
