Honeywell ML4135 HVAC, Fast-Acting, Two-Position Actuators

HVAC, Fast-Acting, Two-Position Actuators

The Fast-Acting, Two-Position Actuators are spring return direct coupled actuators (DCA) with an integral junction box for on/off damper control.

• Integral spring return
• -40 C to 130 F (-40 C to 54 C) operating temperature range
• No audible noise during holding
• Electronic circuitry provides efficient operation while eliminating the need for limit switches
• Ninety-five degree angle of rotation
• Die-cast aluminum housing. Housing design allows flush mounting to damper
• Integral junction box with three conduit openings eliminates need for separate wiring box
• Direct mounting to 3/8 or 1/2 in. round or square shaft
• Not intended for smoke control systems
