Special electric gate valve for Coal Safety Mining Area

Special electric gate valve for Coal Safety Mining AreaProtection level：

The protection level is IP68, making it one of the few enterprises with mining coal safety certificate and explosion-proof certificate. Mining explosion-proof electric gate valves are suitable for flammable and explosive environments, with high safety factors, strong operational functions, 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.

Special electric gate valve for Coal Safety Mining AreaStructure and characteristics:

1. The selection of materials is meticulous, in compliance with relevant domestic and international standards, and the overall quality of the materials is high.

2. Meets the requirements of * standard, with reliable sealing, excellent performance, and beautiful appearance.

3. The sealing pair is advanced and reasonable, and the sealing surfaces of the gate and valve seat are welded with different hardness of Slite cobalt based hard alloy. The sealing is reliable, high hardness, wear-resistant, high temperature resistant, corrosion-resistant, scratch resistant, and has a long service life.

4. The valve stem has undergone quenching and surface nitriding treatment, exhibiting excellent corrosion resistance, abrasion resistance, and wear resistance.

5. Adopting a wedge-shaped elastic gate structure, thrust bearings are installed on the medium and large diameters, with low friction, and equipped with manual impact for easy and smooth opening and closing.

6. Various piping flange standards and flange sealing surface forms can be adopted to meet various engineering needs and user requirements.

The MZ series explosion-proof electric gate valve for mining is easy to install, easy to debug, and does not require maintenance for several years after debugging and operation. It is compatible with the KXBC series 12 × 15, 3 × 15/660 (380) DZ or KXBC-15/660 (380) DZ explosion-proof electric device control box for mining, and can be connected to the pump room automation system through communication.
