373-03115

The Siemens Flowrite 599 Series 373-03115 is engineered as a control valve assembly featuring an integrated electric actuator. The actuator, identified as SAX81.03U, enhances the responsiveness and precision of the system. Its trim is constructed from stainless steel, contributing to its resilience and ability to withstand operating conditions effectively.

For voltage requirements, this assembly functions on either 24 Vac or 24 Vdc, with compatibility for input frequency measurements ranging between 45 and 65 Hz. It holds an IP54 rating, offering a degree of protection against dust and water ingress, making it suitable for various installations. The ambient operating temperature for this valve assembly spans from -5 to 55 °C, while storage conditions can fluctuate between -15 to 55 °C. This flexibility allows it to perform in diverse settings.

Humidity tolerance for the 373-03115 ranges from 5 to 95% RH (non-condensing), which ensures reliable operation in moist environments. The maximum permissible medium temperature that this valve can manage is up to 130 °C, providing versatility in applications involving heat.

The control valve assembly delivers significant positioning force, rated at 800 N (180 lbf), ensuring effective valve operation. Its maximum supply fuse rating is 10 A (slow), protecting the circuitry. The valve line size is set at 1-1/2 inches (40 mm), establishing compatibility with various piping systems, and the flow coefficient measured at 25 Cv supports efficient fluid movement within the process.
