Siemens GVD226.1U 120V 200 lb-in Spring Return 2-Position Fire & Smoke Actuator

Description

The Siemens GVD226.1U is a 120-volt, spring-return, 2-position damper actuator engineered specifically for fire and smoke control applications in commercial HVAC systems. Delivering 200 lb-in of torque, this actuator provides the reliable, fail-safe performance required in life-safety damper installations, automatically returning the damper to its safe position upon power loss.

Key Features

• Operating voltage: 120V AC
• Torque output: 200 lb-in for dependable damper closure
• Spring-return (SR) fail-safe operation — returns to safe position on power loss
• 2-position control (open/closed) for straightforward fire and smoke damper applications
• Designed for fire and smoke damper duty in commercial and industrial HVAC systems
• Siemens Building Technology quality construction for long service life
• Direct-coupled mounting for simplified installation

Application

The GVD226.1U is ideal for use with fire and smoke combination dampers in air handling systems, mechanical rooms, and duct penetrations where building and fire codes require automatic damper actuation. The spring-return mechanism ensures the damper moves to its fail-safe position whenever power is interrupted, making it a critical component in life-safety HVAC designs.
