Product Description

SAMSON 5825-13 Electric Actuator – 230V AC Fail-Safe Linear Valve Actuator

The SAMSON Type 5825-13 Electric Actuator is a high-performance electric linear actuator manufactured by SAMSON AG, Germany. It is specially designed for automatic operation of control valves in HVAC systems, industrial process automation, heating systems and energy management applications.

Unlike the SAMSON 5824 series, the SAMSON 5825-13 features an integrated fail-safe mechanism with a spring assembly and electromagnet. In the event of power supply failure, the actuator automatically moves the connected valve to its predefined safety position, helping protect industrial processes and equipment.

The 5825-13 features a three-step control system with a faster synchronous motor and maintenance-free gearing. It offers a rated travel of 6 mm, a maximum actuator thrust of 500 N and a fast stroking speed of approximately 0.36 mm/s.

This actuator is suitable for applications requiring automatic valve positioning and emergency safety operation. It is particularly useful in industrial heating systems, HVAC installations, boiler systems, heat exchangers, water circulation systems and building management systems.

For industrial customers in Bangladesh, the SAMSON 5825-13 provides a reliable solution for control valve automation where fail-safe operation is an important requirement.
