BELIMO LM24A-VST

Precise damper control is vital in modern HVAC systems to maintain airflow, comfort and energy efficiency. The Belimo LM24A‑VST actuator tackles this by delivering modulating control (instead of just open/close) with built‑in feedback, making it ideal for dynamic zoning, variable‑air‑volume (VAV) units or balancing ventilation systems. With a torque rating of 5 Nm, it’s suitable for dampers of approximately 1 m²—common in commercial and large residential installations. The 2–10 V control input allows integration with building‑automation systems or local control boards, while the 2–10 V feedback output gives real‑time position data—helpful for diagnostics and ensuring the actuator is performing correctly. Its universal clamp (6–20 mm) simplifies retrofits or diverse damper shafts. Compared to conventional on/off actuators, the LM24A‑VST provides smoother control, improved comfort and reduced noise from abrupt damper movements. Moreover, the VST connector reduces installation time and minimizes wiring errors, which is a plus for contractors and installers in busy service environments. Housed in an IP54 rated enclosure, it offers reliable performance in typical HVAC zones indoors. In summary, for HVAC professionals seeking a dependable, installation‑friendly modulating actuator with feedback and fast setup, the LM24A‑VST stands out.
