Explosion proof intelligent electric actuator

Comprehensive information and market situation of explosion-proof intelligent electric actuators:
1、 Product type and price range
Mining explosion-proof electric gate valve
Mainstream models such as MZ941H-16C are suitable for underground coal mine environments, with a price range of 1500-3150 yuan (DN200 caliber).
The high-end models (such as ZBK941H-40 DN200) support intelligent control and are priced at approximately 3830 yuan.
Intelligent adjustable electric actuator
The price of some rotary electric torque 900 models (such as DQW90-0.5WB) is about 2844 yuan.
The price of intelligent integrated models (such as Z15-24ZB) is about 2903 yuan.
2、 Technical features
Explosion proof certification: MA coal safety certificate and explosion-proof certificate (such as dI/dIIBT4 level) are required, with a protection level of IP68.
Material and process: The valve body is made of 304 stainless steel, and the sealing surface is welded with Stellite hard alloy, which is wear-resistant and corrosion-resistant.
Intelligent control: Some models support 485 communication, 4-20mA analog control, and are compatible with DCS systems.
3、 Application scenarios
Underground water distribution system: such as PZI-400 model used for flow control in the water pump room.
Gas pipeline: Explosion proof solenoid valve (AC220V/24V) is suitable for flammable and explosive gas environments.
Automation transformation: Replace manual valves and achieve remote control (such as the case of Pingmei No.2 Mine).
4、 Industry standards
Corrosion resistance: Stainless steel valves must comply with the GB/T 12234-2019 standard.
Safety regulations: Electric actuators must meet AQ standards (such as ZB60-24 mining explosion-proof type).
If specific model parameters or procurement channels are required, further explanation of application scenario requirements can be provided.
