IIIMA certified 380V/660V mining explosion-proof valve electric actuatoroptionPrecautions

Valve matching: Select the actuator torque based on the valve torque and diameter (with a margin of 1.5 times).

Explosion proof level: Confirm the classification of mine gas (such as M1/M2 level in Class I coal mines).

Power and signal: voltage level (AC 380V/660V), control signal (passive contacts/24VDC).

Installation method: Vertical or horizontal installation, taking into account the connection standards between the actuator and the valve (ISO 5211, etc.).

4MA certified 380V/660V mining explosion-proof valve electric actuatorCore Features

Explosion proof and protective design

Explosion proof certification: usually compliant with Exd I Mb (mining explosion-proof type) standards, suitable for explosive environments such as methane and coal dust.

Protection level: IP65/IP67, dustproof and waterproof, suitable for wet and dusty mining conditions.

Switch control mode

Two position control (fully open/fully closed), some models support the middle position (such as 25%/50%/75% opening).

Trigger actions through external signals (such as PLC, DCS) without the need for complex operations such as adjusting flow rate.

Power and Transmission

Motor type: High torque three-phase asynchronous motor (380V/660V), suitable for voltage fluctuations in mines.

Reduction mechanism: worm gear or gearbox, with high output torque (up to thousands of Nm), suitable for high-pressure differential valves.
