1. Product Title
SAMSON 5825-10 Electric Actuator 500N, 6mm Stroke, 230V AC, Fail-Safe Linear Valve Actuator
2. Product Description
The SAMSON 5825-10 Electric Actuator is a high-performance German-engineered electric linear actuator designed for precise valve control in industrial automation, HVAC systems, heating, ventilation, air conditioning, and process engineering applications.
Manufactured by SAMSON Germany, the Type 5825-10 features an integrated fail-safe mechanism with spring return functionality. In the event of power supply failure, the actuator automatically moves the connected control valve to its predetermined safety position.
The actuator provides a rated travel of 6 mm and an extending thrust force of 500 N. Its standard three-step control operation, maintenance-free gearing, and reliable synchronous motor ensure dependable operation in industrial environments.
One of its major advantages is its automatic fail-safe operation. When the electrical supply is interrupted, the spring mechanism moves the actuator stem to the extended position within approximately 4 seconds, helping protect industrial processes and equipment.
The SAMSON 5825-10 is suitable for compatible SAMSON control valves used in industrial heating systems, chilled water applications, water treatment plants, energy management systems, and building management systems (BMS).
Tech Lab Bangladesh Engineering supplies industrial automation equipment and valve control solutions for the Bangladesh market.
