Mcquay Daikin 111047701 Actuator

The McQuay Daikin 111047701 Actuator is a heavy-duty 120V HVAC valve actuator designed for precise flow control in commercial air handling units and chilled water systems. This 150# torque rating unit utilizes non-spring return (NSR) logic and floating control signals to manage valve positioning without the risk of immediate closure upon power loss. Engineered for high-static pressure applications, the 111047701 includes dual auxiliary switches (2Aux), allowing technicians to easily integrate end-switch feedback into the BAS for proof of closure or to trigger external equipment like pumps or fans. This OEM McQuay part ensures exact fitment and timing sync within Daikin Applied systems, maintaining the hydraulic balance necessary for optimal heat transfer. Its robust housing protects internal gears against mechanical wear, providing reliable modulation in demanding mechanical rooms where floating point actuators are the standard for multi-stage environmental control.

• 150 lb-in Torque Output: Delivers the mechanical force required to overcome high differential pressures in large-diameter piping.
• Non-Spring Return Logic: Maintains the last commanded position during power interruptions, preventing sudden system surges.
• Integrated Dual Auxiliary Switches: Simplifies sequence-of-operation wiring by providing dry contacts for status monitoring.
• Standard 120V Architecture: Eliminates the need for external Step-down transformers in high-voltage control cabinets.
• High-Compatibility OEM Casting: Specifically engineered for Daikin 111047701 specifications to ensure zero-clearance issues during field replacement.

Is the 111047701 compatible with 24V control circuits?
No, this specific model is a 120V AC actuator. Attempting to power this unit with 24V will result in failure to operate; always verify your control voltage at the terminal strip before installation.

Can the auxiliary switches be adjusted in the field?
Yes, the 2Aux switches allow for field-adjustable setpoints, enabling technicians to define the exact degree of rotation where the switch closes to confirm valve position.

What is the benefit of a floating control signal for this actuator?
A floating act. allows for incremental positioning between fully open and fully closed without the complexity of a 0-10VDC or 4-20mA setup, making it ideal for standard three-wire control configurations.
