Siemens Building Technology GVD226.1U Actuator

The Siemens Building Technology GVD226.1U is a heavy-duty 120V spring return actuator engineered specifically for fire and smoke damper applications. Delivering a robust 200 in-lb torque, this fast-acting actuator is the industry standard for lifecycle safety in commercial HVAC systems, ensuring rapid response during emergency shutdown protocols. As a two-position control motor, it provides reliable open/close operation, making it a critical component for UL555 and UL555S compliant installations. Designed to handle the high static pressures found in tiered smoke evacuation control zones and stairwell pressurization setups, the GVD226.1U ensures that dampers reach their fail-safe position immediately upon power loss. Built with a durable die-cast aluminum housing, this unit is designed to withstand the rigorous thermal requirements of life safety dampers while maintaining precise airflow control. For contractors managing building automation systems, this Siemens actuator offers seamless integration for reliable smoke containment strategies.
