SAMSON 5825-33 Electric Actuator 230V AC | 280N | 15mm Stroke | Fail-Safe Valve Actuator

Product Description

SAMSON 5825-33 Electric Actuator – 230V AC High-Speed Fail-Safe Linear Valve Actuator

The SAMSON Type 5825-33 Electric Actuator is a high-quality industrial electric linear actuator manufactured by SAMSON AG, Germany. It is designed for reliable and precise operation of control valves used in HVAC systems, industrial heating and cooling, building management systems (BMS) and process automation applications.

The SAMSON 5825-33 features an integrated fail-safe mechanism that automatically moves the actuator stem to its predefined safety position when the electrical power supply fails. This helps protect industrial processes and equipment during unexpected power interruptions.

This model offers a rated travel of 15 mm, an actuator thrust of 280 N and a form-fit valve connection. It is equipped with a faster synchronous motor and maintenance-free gearing, providing a stroking speed of approximately 0.36 mm/s and a normal transit time of approximately 45 seconds.

The 5825-33 is a three-step control version without a digital positioner. Its fail-safe configuration is designed for actuator stem extension, with an emergency fail-safe transit time of approximately 7 seconds.

For industrial customers in Bangladesh, the SAMSON 5825-33 is suitable for HVAC automation, boiler control systems, heat exchangers, industrial temperature regulation, hot water circulation and automatic control valve applications.
