Explosion Proof Quarter-Turn Electric Actuator
,Ex db IIC T6 Gb Electric Actuator
,Hazardous Location Explosion Proof Actuator
The GRAT explosion-proof quarter-turn electric actuator is engineered for hazardous and flammable locations, carrying Ex db IIC T6 Gb and Ex tb IIIC T80°C Db certifications. It delivers reliable valve, pipeline, and equipment control in petrochemical plants, coal mines, and pharmaceutical facilities.
Specially designed casings, motors, and dedicated sealing components prevent explosions caused by electric sparks or high temperatures. The actuator withstands high temperatures, pressure, and flammable substances, providing maximum safety and effective protection in demanding environments.
The GRAT explosion-proof actuator features a robust aluminum alloy and stainless steel housing for maximum durability. Its explosion-proof enclosure integrates a heavy-duty gear set, limit switch assembly, and potentiometer, providing reliable transmission and multiple feedback options for precise valve control.
