Product Description P/N: TR24-SR US
Description
The Belimo TR24-SR US is a non-spring-return rotary valve actuator designed for modulating control of compatible HVAC valves. Operating on 24 VAC/VDC power, it responds to a 2–10 VDC signal and completes 90° of travel in 90 seconds. Its 0.5 W operating power consumption supports low-power valve positioning in heating and cooling systems.

Information About TR24-SR US
The TR24-SR US is part of Belimo’s TR Series of compact electric valve actuators for hydronic HVAC applications. Its non-fail-safe mechanism provides motor-driven positioning without an automatic spring-return function. A direction-selection switch allows the actuator’s rotation to match the required valve response, while a push-down handle enables manual adjustment. Electronic overload protection operates throughout the full rotation range, and an indicator integrated into the handle shows valve position.
Key Features:
- Modulating Control: Positions compatible valves in response to a 2–10 VDC control signal.
- Dual Power Compatibility: Operates from either 24 VAC or 24 VDC supplies.
- Low Power Consumption: Requires 0.5 W during motor operation.
- Non-Spring-Return Design: Provides electric positioning for applications that do not require mechanical fail-safe return.
- Current Signal Option: Accepts 4–20 mA control with an external ZG-R01 500-ohm resistor.
- Selectable Direction: Includes a switch for selecting the motor’s direction of rotation.
- Manual Positioning: Provides a push-down handle for manual valve adjustment.
- Quarter-Turn Travel: Delivers 90° rotation with a motor running time of 90 seconds.
- Electronic Protection: Protects the actuator against overload throughout its operating travel.
- Integrated Indicator: Shows valve position directly at the manual handle.
The TR24-SR US delivers the reliability and precision required for proportional valve positioning in commercial hydronic HVAC systems.
