Overview

Electric valves used in coal mines are mainly used for fluid control in flammable and explosive areas underground or on the ground, and must meet safety requirements such as explosion-proof and explosion-proof.

Product Details

1Electric valves for coal minesProduct Introduction

Mainly used for fluid control in coal mines or flammable and explosive areas on the ground, it must meet safety requirements such as explosion prevention and isolation. The following are the main product types and characteristics:

Explosion proof electric gate valve

Adopting mining explosion-proof electric device, supporting DCS system control, suitable for coal mine surface and non mining working face. It has explosion-proof level BT4 and IP68 protection level, and can be connected with PLC and SCADA systems to achieve remote automation control. ‌

Mining explosion-proof butterfly valve

Specially designed for coal mine gas pipelines, compliant with MA coal safety certification, supporting solid-state relay drive (spark free), suitable for flammable and explosive environments. The explosion-proof level is dIIBT4, the pressure range can reach 1.6MPa, and the diameter covers DN20-DN350.

Suitable for solid material control such as coal and powder, adopting lightweight design, supporting bidirectional cutting and flow regulation. Supports manual, pneumatic, and electric multi-mode driving, with flexible installation angles, suitable for metallurgical, mining, and other scenarios.

The above products must pass the Coal Safety Certification (MA) and Explosion proof Certification (Ex d/Ex tD) to ensure safety in special working conditions such as coal mines. ‌

　　Electric valves for coal minesThe core advantages of are mainly reflected in four aspects: safety performance, automation control, environmental adaptability, and maintenance convenience:

safety performance

The explosion-proof electric valve adopts an explosion-proof shell design and anti-static structure. It has passed Ex d/Ex tD certification and can effectively prevent sparks or high temperatures caused by electrical equipment failures, ensuring safe use in flammable and explosive environments. ‌

Automation control

Supports remote control and centralized control, and can achieve valve opening adjustment, timed opening and closing, and other functions through PLC, DCS, and other systems. The response speed is fast (usually 6-12 seconds for opening and closing), adapting to the needs of automated production.
