DCL compact electric actuators are widely used with temperature control valves on ships. These electric temperature control valves are primarily applied in the automatic regulation of fresh water, seawater, or lubricating oil within cooling systems for generators, diesel engines, and turbines.

Thanks to the actuator’s high positioning accuracy (error ≤1%), the temperature control precision can be maintained within ±1°C.

Marine environments present strong electrical surges and electromagnetic interference due to the independent onboard power systems. To ensure stable operation under such conditions, all DCL actuators undergo strict EMC testing to meet the demanding requirements of marine applications.

DCL actuators are rigorously tested and certified:

• CSA certified to UL and CSA standards

• CE marked and RoHS 3.0 compliant, verified by SGS
