Explosion-Proof Quarter-Turn Electric Actuator

Description

Explosion-proof Structure and Performance

Discover the robust performance of our Explosion-Proof Quarter-Turn Electric Actuator, featuring a high-level protection rating of ExdIBT4. This actuator is designed for reliable operation in hazardous environments, ensuring safety and efficiency. With a wide range of torque capabilities and compatibility with various valve types, it’s the ideal solution for demanding industrial applications

The explosion-proof structure of HEX series products complies with the relevant provisions of GB3836.1-2021″Explosive AtmospheresPart1:Equipment-General Requirements”and GB3836.2-2021″Explosive Atmospheres Part2 Equipment Protection by flameproof Enclosures ‘d”.and adopts a whole machine explosion-proof structure. The explosion-proof shell composed of various explosion-proolcomponents of the product can withstand the explosion pressure generated by the explosive gas mixture inside the shell during anexplosion,and can prevent the explosion inside the shel from spreading to the surrounding explosive gas environment outside theshel.lin other words, when an explosion occurs inside the product, it will not propagate to the outside ofthe shell and ignite the explosi-ve gas mixture outside the shell.

Explosion-proof grade

The explosion-proof rating of this product is: ExdIBT4

Where: Ex-explosion-proof marking; d-explosion-prooftype,i ndicating”flameproof”: -equipment category, indicating electrical equip.ment for explosive gas environments other than coal mines:B-explosion level, which determines the dimensions(width and gapof the explosion-proof joint surfaces of the actuator. T4-temperature class,indicating the maximum surface temperature allowed for the actuator is 135°C. In Appendix B of GB3836.1-2021, detailed levels and temperature classes of combustible gases and vapors are listed
Users may refer to it if necessary.
Special attention: The type and group of explosive substances surrounding the location where the product is used must be consistentwith the explosion-proof medium allowed by the product, otherwise, the explosion-proof effect cannot be achieved.

Precautions for use

Pay attention to the prompts on the warning labels. It is strictly prohibited to open any cover while live in the presence of flammableand explosive gases ( i.e.,opening the explosion-proof chamber of the product).
The explosion-proof glass is part of the explosion-proof structure and should not be disassembled or impacted with hard objects during use. When any explosion-proof parts of the product are damaged, they should be replace dimmediately. Before qualified parts are installed, the product should not be operated electrically. The product nameplate and warning labels must not be torn off or lost,and the text on them should remain clear.
