Non-Spring Return Actuators

Used to control dampers in applications such as variable air volume (VAV) terminal units and for mounting on ball valves; suitable for use with SPDT or floating thermostats or building automation controls.

This non-spring return direct-coupled damper actuator provides modulating and floating/2-position control for: air dampers, VAV units, air handlers, ventilation flaps, louvers, and reliable control for air damper applications with up to 10 sq. ft./ 44lb.-in. (5 Nm) and 20 sq. ft./88 lb.-in. (10...

This non-spring return direct coupled damper actuator provides modulating and floating/2-position control for air dampers, VAV units, air handlers, ventilation flaps, louvers, and reliable control for air damper applications with up to 20 sq ft/88 lb-in. (10 Nm) (seal-less damper blades; air...

These direct coupled damper actuators provide adjustable modulating control for: air dampers, VAV units, air handling units, ventilation flaps, louvers, and reliable control for air damper applications with up to 4.6 m2/50 sq ft (seal-less dampers; air friction-dependent).

These direct coupled damper actuators provide adjustable modulating control for air dampers, VAV units, air handling units, ventilation flaps, louvers, and reliable control for air damper applications with up to 7.9 m2/85 sq ft (seal-less dampers, air friction-dependent).
