Electric valve actuator ELC 250SR

linearsingle-acting with return springIP54

Product overview
The ELC 250SR electric linear actuator is designed for safety-critical valve applications requiring a reliable fail-safe action. It delivers 2.5 kN of thrust and incorporates a spring-return mechanism that repositions valves on power loss. With up to 40 mm stroke and adjustable actuation speeds, it supports fast and controlled operation in district heating and other temperature-sensitive systems.
