Tekmar Controls 743 Actuating Motor
The Tekmar Controls 743 Actuating Motor is a specialized 24V floating action actuator engineered for precise integration with tekmar brass mixing valves (series 710 through 724). Delivering a consistent 10 N·m (88 in-lbs) of torque, this motor ensures reliable modulation for both residential hydronic systems and large-scale commercial building automation. The 743 features an electrically limited shaft rotation of 90° with a run time of 117 seconds at 60 Hz, allowing for smooth, incremental adjustments that prevent thermal shock and balance heating loads effectively. Housed in a NEMA 1 polycarbonate enclosure, it is purpose-built for indoor environments ranging from 32°F to 122°F. Whether you are servicing a multi-family complex or a small commercial facility, this hydronic mixing valve actuator provides the mechanical force required for accurate floating action control in critical temperature-mixing applications.
Key Benefits for the Contractor:
- Direct Compatibility: Pre-configured for seamless mounting on tekmar 710-724 brass mixing valves, reducing field installation time.
- High Torque Output: Rated at 88 in-lbs to handle valve friction and ensure positive closure even in older hydronic loops.
- Precise Modulation: The 117-second run time permits fine-tuned temperature mixing for superior occupant comfort and energy efficiency.
- Robust Construction: Polycarbonate enclosure provides reliable protection for the 24 V AC motor in mechanical room environments.
- Standardized Control: Operates on a standard 3-wire floating signal common in professional-grade HVAC control systems.
Technical FAQ:
How do I wire the Tekmar 743 for floating action?
The motor uses a 24 V AC signal across three terminals: one common, one for clockwise rotation (Open), and one for counter-clockwise rotation (Close).
Can the 743 handle vertical or horizontal installations?
Yes, the actuator can be mounted in various orientations, provided it is used with compatible tekmar brass mixing valves and remains protected from water in a NEMA 1 environment.
What happens if the motor reaches the end of the 90-degree stroke?
The shaft rotation is electrically limited at 90° to prevent mechanical binding and protect the internal gear train of the actuating motor.
