MXG461B32-12

The Siemens part number MXG461B32-12 is engineered as a modulating control valve, utilizing a magnetic actuator for responsive operation. This valve is capable of handling water temperatures between -20°C and 130°C, catering to diverse application needs. Its voltage specifications include 24 Volts AC with a tolerance of ±20%, along with compatibility for 20 to 30 Volts DC. The input frequency for operation ranges from 45 to 65 Hz. With an IP31 rating in accordance with EN60529, this valve provides protection against dust and moisture ingress.

This valve has an operating temperature range from -5°C to 45°C, while maintaining the same range for storage. It is also robust enough to endure transport temperatures reaching as low as -25°C and as high as 70°C. The valve operates efficiently within a humidity range of 5 to 95%, which is non-condensing, ensuring that the valve remains functional under varying environmental conditions.

Constructed from red bronze for the body and cover flange, this valve also features a stainless steel seat and EPDM stem seal, ensuring durability and corrosion resistance. It has a power consumption rating of 43 VA or 20 W. Control options include a signal type configurable to 0/2 to 10 Volts DC, 0/4 to 20 mA, or through a 0-20 Volts DC phase-cut mechanism. The close-off pressure is rated at 87 psi, while the maximum operating differential pressure is 40 psi, enabling reliable performance under specified conditions. The flow coefficient (Cv) of 14 allows the valve to manage different flow rates effectively.
