Product Overview
The Ingersoll Rand 47704439001 / 47690563001 Temperature Control Valve Repair Kit is a professional maintenance kit designed to restore the performance of the temperature control valve (thermostatic valve) used in Ingersoll Rand oil-injected rotary screw air compressors. The kit includes the essential wear components required to overhaul the valve, helping maintain proper oil temperature regulation, efficient cooling performance, and reliable compressor operation.
In a rotary screw air compressor, the temperature control valve is responsible for regulating the flow of lubricating oil between the oil cooler and the compressor lubrication circuit. During cold starts, the valve bypasses the oil cooler, allowing the lubricant to warm up quickly and reach the optimum operating temperature. As the oil temperature increases, the valve gradually directs oil through the cooler to prevent overheating and maintain stable operating conditions.
Over time, continuous thermal cycling, pressure fluctuations, oil contamination, and normal mechanical wear can reduce the efficiency of the valve. Worn seals, springs, and internal valve components may lead to unstable oil temperatures, reduced cooling efficiency, increased compressor wear, and higher energy consumption.
The 47690563001 Temperature Control Valve Repair Kit provides replacement components that restore proper valve operation without replacing the complete valve assembly. Regular preventive maintenance helps extend compressor service life, improve lubrication efficiency, reduce operating costs, and minimize unplanned downtime.
With compact dimensions of 100 × 15 × 80 mm and an approximate weight of 0.15 kg, this repair kit is easy to transport, store, and install during scheduled compressor maintenance.
Typical applications include manufacturing facilities, automotive production plants, mining operations, pharmaceutical factories, food and beverage processing, chemical processing plants, woodworking industries, textile mills, power generation facilities, and general industrial compressed air systems.
