Description
The Siemens GDE131.1T is a 24V non-spring return (NSR) damper actuator engineered for precise three-position control in commercial HVAC and building automation applications. Delivering 44 lb-in of torque, this actuator is well-suited for medium to large damper assemblies where dependable positioning and long service life are essential. The integrated terminal strip simplifies field wiring and reduces installation time, making it a preferred choice for mechanical contractors and building automation technicians alike.
As part of Siemens Building Technology’s GDE actuator series, the GDE131.1T is designed to integrate seamlessly into building automation systems (BAS), providing accurate damper modulation for air handling units, VAV systems, and mixed-air applications. Its non-spring return design retains the last commanded position upon power loss, which is ideal for applications where a fail-in-place response is required.
