Siemens Building Technology MXG461.15-0.6U Valve

The Siemens MXG461.15-0.6U is a high-performance modulating magnetic control valve engineered for precision in chilled and hot water systems. Designed for veterans who demand rapid response times, this 1/2 inch NPT valve features a 0.7 Cv rating and a magnetic actuator that delivers a positioning time of less than two seconds. This speed ensures immediate load correction and superior stability in closed-loop circuits. The integrated electronics module supports versatility in the field, allowing for switch-selectable control signals including 0-10 VDC, 2-10 VDC, or 4-20 mA. Contractors can also toggle between linear or equal-percentage flow characteristics to match specific application requirements.

Built for reliability in demanding HVACR environments, the magnetic drive utilizes a wear-free inductive stroke measurement system, eliminating the friction points common in traditional motorized actuators. The spring return fail-safe mechanism ensures the A to AB path closes automatically upon power loss, protecting critical equipment. Physical installation is streamlined with NPT union fittings, and the robust construction supports medium temperatures ranging from 34°F to 266°F. This unit is optimized for mixing or straight-through applications—specifically for mixing arrangements—offering a high 1000:1 stroke resolution for unmatched modulating accuracy.

• Rapid Response: Magnetic induction technology allows for a positioning time under 2 seconds for precise temperature control.
• Maintenance-Free Design: Frictionless magnetic drive and inductive stroke measurement eliminate mechanical wear and the need for regular servicing.
• Field Flexibility: DIP switches allow for quick selection of input signals (VDC/mA) and flow characteristics (Linear/EQ%) without additional tools.
• Fail-Safe Protection: Reliable spring return functionality ensures the valve returns to a closed position during de-energization.
• Durable Construction: Rated for high-temperature water and chilled systems, featuring a 72 psi close-off pressure.

Can this valve be used for steam applications?
No, the MXG461.15-0.6U is specifically designed for chilled and hot water in closed circuits. It is not rated for steam services.

What is the purpose of the integrated LED?
The two-color LED provides immediate visual feedback on the operating status, including power, calibration progress, and potential error states.

Does it require a separate actuator?
No, this model is a factory-calibrated, integrated assembly where the magnetic actuator and valve body are one unit.
