It incorporates Belimo’s MFT multi-functional technology, allowing field configuration of control signals and operating behavior to match system requirements. The actuator is designed for non fail-safe applications where continuous powered positioning is required, providing stable torque output across its operating range. A rugged NEMA 4X enclosure protects internal components, supporting installation in harsh indoor or outdoor environments. Key Features High Torque Valve Actuation: Delivers 1335 in-lb of torque to reliably drive large control valves in high-demand hydronic applications. Non Spring Return Operation: Provides powered positioning without a fail-safe spring, suitable for systems where return on power loss is not required. MFT Programmable Control: Supports multiple control modes including 2…10 V, 4…20 mA, PWM, on/off, and floating point for broad system compatibility. Configurable Input Impedance: Optimized impedance values support stable signal processing for current loop and PWM control schemes. AC And DC Power Compatibility: Operates on both 24 VAC and 24 VDC supplies to simplify system design and power distribution. Rugged NEMA 4X Housing: Sealed enclosure protects against moisture, dust, and corrosion in challenging mechanical room or outdoor installations. Maintenance-Free Design: Engineered for long service life with minimal servicing requirements. The SY3-24MFT delivers the reliability and precision required for high-torque valve control in advanced HVAC and hydronic systems.
