660V mining electric gate valveThe selection of materials is meticulous and meets relevant domestic and international standards. The overall quality of the materials is high, meeting the requirements of * standards. The sealing is reliable, the performance is excellent, the appearance is beautiful, the sealing pair is advanced and reasonable, the gate and valve seat are sealed reliably, with high hardness, wear resistance, high temperature resistance, corrosion resistance, good scratch resistance, and long service life.

The 660V mining electric gate valve stem has undergone quenching and surface nitriding treatment, and has good corrosion resistance, abrasion resistance, and wear resistance. It adopts a wedge-shaped elastic gate structure, with thrust bearings installed on the medium and large diameters, low friction, and equipped with manual impact. It can be opened and closed easily and freely, and can adopt various piping flange standards and flange sealing surface forms to meet various engineering needs and user requirements.660V mining electric gate valveThe direction of motion is perpendicular to the direction of the fluid, and the gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve has two sealing surfaces, and the commonly used mode gate valve has two sealing surfaces that form a wedge shape. The wedge angle varies with the valve parameters, usually 50, and when the medium temperature is not high, it is 425 ℃.

The gate of the 660V mining electric gate valve can be made as a whole, called a rigid gate, or as a gate that can produce slight deformation to improve its processability and compensate for the deviation of the sealing surface angle during the processing. This type of gate is called an elastic gate. 660V mining electric gate valve is suitable for applications where the medium is viscous, contains particles, and has fiber properties. It is widely used in industrial automatic control systems such as petroleum, chemical, teaching equipment, light industry, high-pressure equipment, pharmaceuticals, and papermaking, for remote centralized control or on-site control.

The protection level of 660V mining electric gate valve is IP68, which is one of the few * with mining coal safety certificate and explosion-proof certificate. It is suitable for flammable and explosive occasions, with high safety factor, strong operating function, and stable performance.660V mining electric gate valveThere are two types: 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.
