371-03150

The Siemens 371-03150 control valve assembly integrates an electric actuator model SAX61.03U. This assembly is designed to function reliably under a variety of operational environments. Its rated voltage can be either 24 Vac or 24 Vdc, accommodating different power system requirements. The input voltage frequency ranges from 45 to 65 Hz, ensuring compatibility with common electrical systems.

The valve features a 1-1/4 inch (32 mm) line size and includes stainless steel for the trim material, enhancing durability and resistance to corrosion. It boasts a flow coefficient of 16 Cv, signifying its capacity for effective fluid management. Operationally, the assembly can handle ambient temperatures between -5 °C and 55 °C, while also supporting a maximum temperature of 130 °C for the medium it controls.

For storage, the temperature may range from -15 °C to 55 °C, demonstrating its resilience in varied environmental conditions. Additionally, the valve assembly operates effectively within a humidity range of 5 to 95% relative humidity, provided that condensation is absent. The actuator itself generates a positioning force of 800 N (180 lbf), allowing for sufficient control under various load conditions with a positioning time of 30 seconds. Lastly, the IP54 rating confirms its suitability for environments where dust and moisture exposure could be present.
