Belimo PKRXUP-MFT-T Actuator

The Belimo PKRXUP-MFT-T is a high-torque, universal voltage actuator designed for demanding applications requiring 1415 in-lb of torque. This fail-safe globe valve actuator operates on a wide input range of 24 to 240 VAC/DC, providing maximum flexibility for field replacements and new installations. Featuring Multi-Function Technology (MFT), this unit allows for precise terminal configuration of control signals, including 0-10 VDC modulation, PWM, or floating point control. The electronic fail-safe mechanism utilizes internal capacitors to drive the valve to a user-defined safety position during power loss, ensuring system protection without the mechanical failure points of traditional spring-return units. Built with a NEMA 4X / IP66 rated enclosure, the PKRXUP-MFT-T is engineered for survivability in harsh mechanical rooms and outdoor environments, making it a reliable solution for managing large-scale chilled water and steam valve assemblies.

• Universal Compatibility: Operates on any supply voltage from 24V to 240V, reducing the need to stock multiple variations for different job sites.
• Programmable Fail-Safe: Electronic failsafe technology allows for bridge-rectified safety positioning without mechanical springs.
• Rugged Environmental Protection: The NEMA 4X housing protects internal components from moisture, dust, and corrosive elements.
• Advanced Diagnostics: Near Field Communication (NFC) and MFT capabilities allow for rapid field programming and performance monitoring.
• High Torque Output: Delivers 160 Nm (1415 in-lb) to handle large diameter valves and high differential pressures.

How do I configure the fail-safe position on the PKRXUP-MFT-T?
The fail-safe position (Normally Open, Normally Closed, or a specific percentage) is configured via the Belimo Assistant App using NFC or through a handheld ZTH US toolkit.

Can this actuator handle high-temperature steam applications?
Yes, when paired with the appropriate valve linkage and thermal shield, the PKRXUP-MFT-T is suitable for high-pressure steam systems common in industrial HVAC setups.

What control signals are compatible with this model?
The unit is factory-set for 2-10 VDC but can be field-adjusted for 0-10 VDC, 4-20 mA, or on/off control depending on your controller requirements.
