Explosion-Proof Spring Return Fail-Safe Electric Actuators / SE Series
![]() |
Product OverviewSun Yeh explosion-proof electric spring return fail-safe actuators, in addition to normal function (floating control, two-position control, modulating control) are designed to provide fail-safe positioning of valves and dampers upon loss of voltage supply. A mechanical spring set is utilized to position the controlled device to either the fully OPEN or fully CLOSED position, without any external power source. For a two-position type actuator, a mechanical BUFFER is employed at the end of the spring stroke, to reduce the dynamic effects of the spring return system. Our explosion-proof electric actuators can choose the clutch-less and lever-less manual override for standard units to provide full-time manual positioning of the controlled device. The SE series explosion-proof electric actuator is structured as flame-proof and combustible dust-proof. The directive and standards marking is II2GD Ex db IIB T4 Gb, Ex tb IIIC T130°C Db. where it is classified as Zone 1 or Zone 2, containing Group IIA and Group IIB gases, Zone 21 or Zone 22, containing the combustible dust atmosphere or a mixture of explosive gas atmospheres and combustible dust atmospheres. Temperature group T1 to T4. If you want to get more information about our Explosion-Proof Electric Actuator, feel free to contact us as soon as possible! |
