Siemens Building Technology MXG461.25-8.0U Valve
Professional-grade hydronic control requires high precision, and the Siemens MXG461.25-8.0U delivers with a 1-inch NPT magnetic control valve designed for rapid response in closed-circuit systems. This modulating magnetic control valve features a 9.3 Cv flow coefficient and is expert-engineered for chilled water or low-pressure hot water applications where temperature stability is critical. With a positioning time of less than two seconds and 1000:1 stroke resolution, this valve provides exact flow regulation that standard motorized actuators cannot match. It supports switch-selectable control signals, including 0-10 Vdc, 2-10 Vdc, and 4-20 mA, ensuring seamless integration with diverse building automation systems. The unit includes a spring-return fail-safe mechanism (A to AB closed) and a manual override handwheel for local control during commissioning or maintenance. Built for longevity, the maintenance-free design utilizes wear-free inductive stroke measurement and a robust cast iron body to handle medium temperatures from 34°F to 266°F.
Key Benefits:- High-Speed Modulation: Achieve sub-two-second positioning for precise temperature control in demanding HVACR loops.
- Versatile Configuration: Factory-calibrated for use as a 3-port mixing valve or a 2-port straight-through valve (using the included blanking flange).
- Superior Resolution: 1:1000 stroke resolution ensures stable flow even at extremely low demand, preventing hunting.
- Universal Compatibility: Field-selectable linear or equal-percentage flow characteristics to match specific heat exchanger requirements.
- Built-in Feedback: Integrated position feedback signal allows for real-time monitoring via the controller.
Can the electronics module be replaced without pulling the entire valve?
Yes, the ASE1 replacement electronics module can be swapped if needed, though the valve body and magnetic actuator are integrated as a single assembly for precision calibration.
What is the maximum pressure rating for this 1" valve?
The MXG461.25-8.0U is rated for PN16 applications with a maximum permissible operating pressure of 145 psi (1000 kPa) and a close-off pressure of 43 psi.
Does this unit come with the necessary fittings?
This specific model (U-version) includes a set of NPT union fittings and the necessary gaskets to simplify threaded pipe connections.
