MXG461.20-5.0U

The Siemens MXG461.20-5.0U modulating control valve is engineered for versatility in flow control applications. With a nominal pressure rating of 232 psi (16 bar), this valve is capable of withstanding significant system pressures. It operates using a voltage rating of 24 VAC and is compatible with 50/60 Hz input frequency. The NEMA 1 enclosure rating indicates that this valve is suitable for indoor use lacking protection against water or dust ingress.

This valve is designed as a mixing/straight-through type, which allows for flexibility in installation and system design. Its configuration can be adjusted for 2-way or 3-way operation, providing the user with options depending on specific requirements. The valve typically operates in a normally closed position, designated as A→AB, which ensures that flow is managed precisely when required.

For connection, the valve employs an external threaded screwed connection measuring 3/4 inches. This connection type is prevalent in many industrial applications, facilitating straightforward integration into existing piping systems. The flow coefficient of 5.8 Cv indicates a favorable throughput, making it suitable for various service conditions.

The body of this control valve is constructed from durable cast iron, supporting its operational integrity in demanding environments. The internal trim comprises a CrNi steel plug paired with a brass seat, contributing to its overall longevity and resistance to wear. Actuation is provided by a magnetic (electromagnetic) actuator, ensuring precise control over flow dynamics.
