Introduction
The Ingersoll Rand 47550997001 47545136001 Temperature-Sensing Valve Maintenance Kit is a service-oriented combination for the New Cobra M90–160 compressor family. The 47550997001 reference identifies an 8,000-hour preventive maintenance package for the air-cooled configuration, while 47545136001 is listed as the associated temperature-sensing valve maintenance kit.
Temperature management is fundamental to the performance of an oil-injected rotary screw compressor. Lubricant inside the compressor performs multiple functions, including cooling, lubrication, and sealing. For these functions to remain effective, the lubricant and associated system components must operate within the intended temperature range.
The temperature-sensing/control valve forms part of this thermal-management strategy. By responding to operating temperature, the valve helps regulate the relevant fluid circuit and supports stable compressor conditions during changing load and ambient conditions.
For an industrial compressor operating for long periods, thermal stability is more than a comfort factor—it is closely connected with reliability. A temperature-control system that does not respond correctly can contribute to abnormal lubricant temperature, inefficient cooling behavior, or temperature-related operating alarms.
The 47545136001 kit is therefore particularly relevant during major scheduled maintenance. Rather than waiting for a temperature-control component to become a source of unplanned downtime, maintenance teams can address the valve assembly during an established 8,000-hour service interval.
The published maintenance listing provides a direct relationship between the two requested references. For New Cobra M90–160 kW equipment, 47550997001 lists 47545136001 as one temperature-sensing valve kit. The same 47545136001 reference is also shown within the corresponding water-cooled and VSD maintenance configurations.
This distinction is useful when purchasing service parts. A temperature-control valve kit should not be selected simply because another valve has a similar physical appearance. Differences in temperature setting, flow characteristics, connection design, and internal construction can make apparently similar parts unsuitable.
Ingersoll Rand's M90–160 product information emphasizes the role of its parts and service organization in supporting installation and maintenance of these compressors. Using the correct service reference therefore helps maintenance teams preserve configuration accuracy throughout the machine's operating life.
When investigating a temperature-related compressor issue, the valve should not automatically be considered the root cause. Temperature sensors, lubricant condition, coolers, airflow, control signals, and other thermal-management components should also be evaluated.
For purchasing departments, the combination of 47550997001 and 47545136001 provides clear maintenance traceability. Recording the compressor model and serial number alongside these references further reduces the risk of selecting a similar but incompatible temperature-control component.
When correctly matched to the machine, 47545136001 provides a focused maintenance solution for the temperature-sensing valve circuit and supports the broader reliability objectives of the 8,000-hour preventive maintenance program.
