Description

DCL compact electric actuators are always used with temperature control valve on ship. Electric control temperature valve is mainly used for auto control of fresh water, sea water or lubricating oil in cooling system, such as generator, diesel engine and turbine etc. Due to the high accuracy(error≤1%) of the actuator’s outdrive positioning, the temperature control can be less than 1℃. Moreover, the surge and electromagnetic interface on the ship are very strong because of the independent power system, all DCL actuators are strictly tested for EMC to meet the severe application.

DCL participates to draft two Chinese national standards, “Marine Electric Control Butterfly Valve” and “Marine Electric Control Ball valve”. Until know, at least 5000 pcs DCL electric actuators are still working on kinds of ships. Actuators are also rigorous tested by CSA per UL and CSA standard. The electric control valves produced by our customer driven by DCL electric actuators have the certifications of DNVGL, LR, BV, NK, KR, RINA, ABS, RS and CCS.
