220VAC Fail Safe Electric Actuator

Thermal overload protection fail safe electric actuator/position keep when lose power

Description

DCL fail safe electric actuator can stay at last know position when power lose, to keep pipe flow and pipe pressure no change. All metal gear train can also suffer high pressure vibration when dangerous situations happen. Heavy duty motor can re-drive valve when power on. Over 10000 times full loaded life cycle with duty rate larger than 80%.

All actuators are rigorous tested and certified by CSA per UL and CSA standard, tested by SGS per CE and RoHS 3 standard.
