Siemens Building Technology GVD226.1U 2-Position Fire & Smoke Damper Actuator Control S/R 200 In-lb 120V

Siemens GVD226.1U Fire/Smoke Damper Actuator is a high precision actuator for precise control of fire and smoke dampers in HVAC systems. This actuator, based on 120VAC, provided such a powerful of torque to reliably produce damper movement in extremes of conditions. The damper has two positions and the control has a spring return feature to hold damper positions at the event of a fire or smoke. The actuator itself is designed to operate in environments of up to 95 percent relative humidity for many applications as it was built to withstand those conditions.The plastic design of the unit's plenum rated design offers longevity and safety in a variety of HVAC configurations, and is designed for easy integration into existing systems.h
