Product Overview
Explosion-proof electric actuator is designed for valve automation in hazardous industrial environments where flammable gases, vapors, or dust may exist.
It is widely used in oil & gas, petrochemical, offshore platforms, LNG terminals, chemical plants, and power generation systems.
The actuator adopts a flameproof enclosure (Ex d type), ensuring internal ignition is fully contained and does not ignite external explosive atmospheres.
This product is designed for EPC industrial projects and mission-critical process control systems, where safety, compliance, and long-term operational reliability are required.

Working Principle
The actuator converts electrical energy into mechanical torque to drive valve operation. Upon receiving a control signal, the motor drives a gear reduction system to rotate the valve stem precisely.
The flameproof enclosure ensures internal ignition is fully contained and prevents ignition of external hazardous gases.
