Siemens Building Technology MXG461.40-20U Valve
The Siemens MXG461.40-20U is a high-performance 1.5" modulating magnetic control valve engineered for precision in closed-circuit chilled and low-temperature hot water systems. Built as a heavy-duty mixing or straight-through valve, it features a factory-calibrated magnetic actuator that eliminates the lag typical of motorized units, delivering a positioning time of less than 2 seconds. With a 23 Cv flow coefficient and a high 1:1000 resolution, this valve provides exceptionally stable control for critical HVACR loops. The integrated electronics module supports multi-signal compatibility, allowing contractors to select between 0-10 Vdc, 2-10 Vdc, or 4-20 mA control signals via onboard DIP switches. Designed for long-term reliability in specialized piping environments, the unit includes a spring-return fail-safe mechanism (A to AB closed) and wear-free inductive stroke measurement. The NPT union fittings ensure a secure fit for standard 1-1/2 inch line sizes, while the maintenance-free O-ring gland and robust cast iron construction withstand medium temperatures up to 266°F.
Key Benefits- High-Speed Response: Magnetic actuator technology enables sub-2-second positioning for immediate load correction.
- Versatile Application: Field-configurable for 2-way straight-through or 3-way mixing arrangements with included blanking flange.
- Industrial Durability: Friction-free inductive stroke measurement and maintenance-free design reduce long-term operational overhead.
- Precise Modulation: Achieving a 1000:1 control resolution ensures hunting is minimized in high-demand circuits.
- Manual Override: Features an integrated handwheel for manual control during commissioning or emergency power loss.
Is this valve compatible with mineral oil-based media?
The standard MXG461.40-20U is designed for water and water-glycol solutions. For systems containing mineral oils, the specific "P" suffix version (MXG461.40-20P) must be used to ensure seal compatibility.
Does the valve require a specific mounting orientation?
The valve must be installed with the actuator in any position from upright to horizontal. It should never be mounted with the actuator projecting downwards to prevent moisture or debris from entering the electronics.
What happens if the control signal is lost?
This model features a mechanical spring-return function. In the event of a power failure or signal loss, the armature automatically returns to the fail-safe position, closing path A to AB.
