Description
Siemens MXF461.65-50U Flanged Magnetic Valve Actuator Overview
The Siemens Building Technology MXF461.65-50U is a commercial-grade flanged valve and magnetic actuator assembly engineered for precise hydronic flow control in HVAC applications. With a 2.5-inch flanged connection and a generous 58 Cv flow coefficient, this unit is well-suited for medium-to-large air handling units, fan coil systems, and chilled or hot water coil circuits where accurate, proportional modulation is essential.
Key Features
- 2.5-inch flanged valve body for secure, leak-resistant pipe connections
- 58 Cv flow coefficient for high-capacity hydronic flow management
- 0–10 VDC proportional control signal for smooth, stepless modulation
- Magnetic actuator design for reliable, low-maintenance operation
- Engineered by Siemens Building Technology for commercial HVAC systems
- Compatible with building automation systems (BAS) and DDC controllers accepting 0–10 VDC input
Application
The MXF461.65-50U is designed for use in commercial and industrial HVAC hydronic systems, including chilled water and hot water distribution circuits. Its proportional 0–10 VDC control input integrates seamlessly with modern building automation and direct digital control (DDC) platforms, enabling energy-efficient, demand-based flow regulation across air handling units, fan coil units, and terminal equipment.
