For electric actuators in petrochemical, chemical, and oil & gas service, one question comes first: how are electrical sparks handled? YEPEF's explosion-proof multi-turn valve electric actuators answer it with the flameproof (explosion-proof enclosure) approach: the electrical parts that may produce sparks and heat in service are enclosed in an enclosure capable of withstanding an internal explosion, without igniting the explosive atmosphere outside.

Qualification comes first: in 2009 YEPEF obtained the national industrial explosion-proof electrical products production license, and the explosion-proof multi-turn actuators fall within its licensed scope. The core torque detection, travel control, and protection design follow the same lineage as the ordinary multi-turn series, with the differences lying in the explosion-proof construction and testing.

Selection should specify the hazardous-area classification and gas temperature class on site, from which the explosion protection grade and enclosure temperature class follow; the flameproof enclosure also dictates dedicated maintenance procedures (cover fastening, flameproof-face protection).
