It is a valve control equipment designed specifically for hazardous environments such as mines, with both explosion-proof and intrinsic safety protection functions. It is suitable for electric control of various types of valves such as gate valves, globe valves, butterfly valves, etc. ‌

IIMining explosion-proof and intrinsic safety integrated valve electric deviceCore Features

Explosion proof structure: Adopting an explosion-proof shell design, it can withstand the pressure generated by the explosion of internal explosive gas mixtures, prevent flames from spreading outward, and ensure the safety of the mine. ‌

Intrinsically safe circuits: Electrical systems that generate electrical sparks and thermal effects under normal or faulty conditions are unable to ignite explosive gas mixtures, reducing the risk of equipment failure.

High protection level: equipped with dust-proof and waterproof functions (such as IP67 protection level), suitable for dust, water vapor, and corrosive substances in complex mine environments. ‌

Applicable scenarios

Valve type: Supports linear motion valves such as gate valves, globe valves, butterfly valves, etc. Some models can be adapted to ball valves (with added deceleration devices). ‌

Application scenario: Automated control of coal mine ventilation systems, drainage systems, and fluid transport pipelines, supporting remote operation and integration with centralized control systems. ‌

Technical Specifications

Environmental adaptation: working temperature -10 ℃~+40 ℃, humidity ≤ 95% (25 ℃), air pressure 86kPa~110kPa.

Control accuracy: It can achieve precise adjustment of valve opening, with errors controlled within a small range. ‌

The device improves maintenance convenience through non-invasive structure, microcontroller programming, and 485 communication interface, and supports data printing function during operation.

The main product advantages are as follows:

Dual protection of explosion-proof and intrinsic safety

Adopting explosion-proof shell design, it complies with GB3836.1-2010 "Explosive Environment Part 1: General Requirements for Equipment" and GB3836.2-2010 "Explosive Environment Part 2: Equipment Protected by Explosion proof Shell" standards, and is suitable for explosive environments such as coal mines underground. Simultaneously equipped with intrinsic safety circuit design, further reducing safety hazards. ‌

intelligent control

Supports remote, on-site, and bus centralized control, equipped with RS485 communication interface and microcontroller programming function, and can achieve parameter adjustment and status monitoring through non-invasive operation. Some models support fast infrared remote control settings, and the display interface supports menu selection in both Chinese and English.

compact structure

Compared to traditional split design, the integrated structure is more compact, reducing cable and space requirements. For example, the ZBK120 model has a small size and light weight, making it suitable for installation in narrow spaces. ‌

Convenient maintenance

Adopting modular design, daily maintenance can be completed without the need for professional tools. Some models are equipped with safety mechanisms such as overheat protection and limit switches to reduce maintenance costs and improve reliability. ‌

Wide applicability

Suitable for various types of valves such as gate valves, butterfly valves, globe valves, etc., covering industrial scenarios such as coal mines, chemicals, and power. The highest explosion-proof level can reach dIIBT4, with a working temperature range of -20 ℃~60 ℃ and humidity adaptability to environments below 95% RH.
