Daikin-McQuay 300046993 General Purpose Valve Actuator - 2-Position 120V 50/60Hz

The Daikin-McQuay 300046993 is an OEM general-purpose 2-position valve actuator designed for use in commercial HVAC systems. Operating on 120V AC at 50/60Hz, this actuator provides reliable open/closed positional control of hydronic valves in heating and cooling applications, including fan coil units, air handling units, and terminal equipment manufactured by Daikin Applied Americas (formerly McQuay International).

As a 2-position (on/off) actuator, it drives the valve to either its fully open or fully closed position in response to a control signal, making it well suited for zone control and scheduling applications where modulating control is not required.

Key Features:

• Voltage: 120V AC, 50/60Hz — compatible with standard line-voltage control circuits
• Control Type: 2-position (open/close) — simple and reliable on/off valve operation
• Application: General-purpose hydronic valve actuation in commercial HVAC systems
• OEM Part: Genuine Daikin-McQuay replacement component for assured compatibility
• Compatibility: Designed for use with Daikin and McQuay fan coil units, air handlers, and terminal systems

The Daikin-McQuay 300046993 is a genuine OEM replacement actuator engineered to maintain the performance and reliability of your commercial HVAC system. Replacing a failed actuator with the correct OEM part ensures proper valve operation, consistent zone control, and long service life.
