The Belimo PRBUP-MFT-T is a non-spring return butterfly valve actuator designed for modulating control in HVAC systems.  It operates on a wide voltage range of 24 to 240 VAC or 24 to 125 VDC, with a nominal frequency of 50/60 Hz.  The actuator consumes 20 W during operation and 6 W in rest position.  This replaces part number SY3-12MFT.

This actuator provides a torque output of 1400 in-lb, suitable for controlling butterfly valves ranging from 2" to 24" in size.  It features MFT (Multi-Function Technology) programmability, allowing for customizable control signals, including BACnet MS/TP, Modbus RTU, MP-Bus, DC 2 to 10 V, and DC 0.5 to 10 V.  Additionally, it includes two SPDT auxiliary switches for versatile integration into control systems.

The PRBUP-MFT-T is built for durability with an IP66/67 and NEMA 4X rated enclosure, ensuring protection against dust and water ingress.  It operates over a 90° angle of rotation with a standard running time of 35 seconds for a full stroke, adjustable between 30 to 120 seconds.  The actuator also includes a manual override feature with a 7 mm hex crank for manual positioning during installation or power loss situations.
