Introduction
The Ingersoll Rand 47552954001 / 23332588 Temperature Control Valve Maintenance Kit is associated with the lubricant-temperature regulation system used on compatible rotary screw compressors.
47552954001 is cataloged as a temperature-control valve maintenance kit for the R90–160 family, including R90–160, IR90–160, and IE R90–160 configurations.
The associated 23332588 component is independently identified as an “ACTUATOR THERMAL 180F TO 198 F.” Parts records therefore provide a clear distinction between the maintenance-kit reference and the individual thermal actuator.
A temperature-control valve is an important part of an oil-injected screw compressor's thermal-management system. Compressor lubricant performs several functions simultaneously, including lubrication, cooling, sealing, and heat removal from internal components. Maintaining an appropriate lubricant temperature is therefore essential to stable compressor operation.
The thermal actuator responds to temperature changes and influences the position of the temperature-control valve. As lubricant temperature changes, the valve regulates the flow path through the cooler and bypass circuit so that the oil can remain within the intended operating range.
The 180°F–198°F designation is particularly useful when identifying 23332588. It represents approximately 82°C–92°C and distinguishes this actuator from thermal actuators designed for other temperature ranges.
If the actuator does not respond correctly, the compressor may experience abnormal lubricant-temperature behavior. A valve that does not provide sufficient cooling can contribute to elevated oil temperature, while excessive cooling can prevent the lubricant from reaching the intended operating temperature.
Oil temperature is also important for moisture management. Maintaining an appropriate operating temperature helps reduce conditions in which condensation can accumulate in the lubricant circuit.
The actuator should therefore be considered together with the complete temperature-control assembly. Problems attributed to a thermal actuator can sometimes originate from a contaminated valve body, restricted oil passages, damaged seals, or problems elsewhere in the cooling circuit.
47552954001 should also be distinguished from other R90–160 maintenance references. For example, 47553880001 is an intake-valve service kit, while 47553885001 is a gearbox maintenance kit. These parts serve different compressor subsystems and should not be substituted for a temperature-control valve kit.
The exact contents of 47552954001 were not independently verified from the available public documentation. It is therefore preferable to describe 47552954001 as a temperature-control valve maintenance kit rather than fabricate a detailed internal bill of materials.
Likewise, complete kit dimensions and shipping weight were not reliably established. The individual actuator's available supplier listing reports a weight of approximately 5.05 lb, but this should not be interpreted as the weight of the complete 47552954001 kit.
The supplied pair is treated as one product listing as requested. Public records independently establish 47552954001 as the temperature-control valve maintenance kit and 23332588 as the 180°F–198°F thermal actuator. The available documentation does not independently establish that 23332588 is the complete bill of materials contained in 47552954001.
