PRODUCT DESCRIPTION
SIEMENS SQM45.295B9 - Electro-Hydraulic Actuator
The SIEMENS SQM45.295B9 is an electro-hydraulic actuator engineered for precise regulation of air dampers and fuel valves in industrial combustion systems. This component provides controlled angular positioning through an integrated hydraulic mechanism, featuring auxiliary switches for end-position signaling and a potentiometer for continuous position feedback. It is specifically designed for integration into burner management systems, industrial furnaces, and process heating applications requiring reliable damper or valve modulation.
