Belimo PRBUP-3-T-200 Actuator

The Belimo PRBUP-3-T-200 is an industrial-grade non-spring return butterfly valve actuator engineered for high-torque applications requiring precise flow control. Operating on a universal supply voltage of 24 to 240 VAC/DC, this electronic fail-safe unit delivers 1420 in-lb (160 Nm) of torque, making it a reliable solution for large-bore piping systems. The multi-function technology (MFT) allows for field adjustment of control signals and feedback, while the integrated 2xSPDT auxiliary switches provide critical end-stop position verification for building automation systems. Designed with a robust NEMA 4X / IP66 enclosure, this actuator handles demanding mechanical room environments and outdoor installations. Its on-off / floating point control capability ensures seamless integration with standard HVAC controllers, providing the high-seat pressure and tight shut-off required in chilled water or condenser water loops.

• Universal Power Input: Accepts 24V to 240V AC/DC for simplified inventory and field flexibility.
• High Torque Output: Rated at 160 Nm (1420 in-lb) to actuate large diameter butterfly valves efficiently.
• Enhanced Durability: NEMA 4X (IP66) housing protects internal components from corrosion and moisture.
• Dual Auxiliary Switches: Includes two built-in SPDT switches for remote position monitoring.
• Manual Override: Features a hand-crank for manual positioning during commissioning or power loss.

Common Questions

How do I wire the Belimo PRBUP-3-T-200 for 120V versus 24V applications?
This actuator features a universal power supply; the internal circuitry automatically detects and compensates for the incoming voltage between 24-240V, eliminating the need for specific wiring taps for different power sources.

Is this actuator suitable for cooling tower applications?
Yes, the NEMA 4X / IP66 rated enclosure is specifically designed to withstand the humidity and atmospheric conditions typical of cooling tower and outdoor environment installations.

Can the control signal be changed from On/Off to Modulating?
While this specific model is configured for On/Off or Floating point control, it utilizes MFT technology, allowing certain parameters to be customized via the Belimo PC-Tool or ZTH US handheld tool.
