Explosion-Proof Multi-Turn Electric Actuator "EPC-4000" for Hazardous Zones

The actuators are designed for operation as part of shut-off valves DN 350...1000 for nominal pressure PN 1,6...10 in outdoor installations and indoors in hazardous areas of class "1" and "2" according to GOST IEC 600079-10-1-2013, in which the formation of vapour and gas-air explosive mixtures of category IIA, IIB of groups T1, T2, T3, T4 according to GOST 316610.0-2014 classification is possible.

EPC-4000 actuators with electronic control unit (ECU) have low weight and small dimensions. The main advantage of these actuators is a compact wave gearbox with intermediate rolling elements having high load characteristics, accuracy, smoothness, reliability and durability.

EPC-4000 can develop torques on the output link up to 4000 Nm. The actuators are equipped with a double-sided torque limiting clutch and have a control unit, which can be easily integrated into a telecontrol system.
