Ingersoll Rand is a world-leading American manufacturer of industrial air compressors, and their rotary screw compressors are widely deployed in manufacturing plants, workshops, and industrial facilities worldwide. The thermostat control valve (thermostatic bypass valve) is a critical oil temperature management component in screw air compressors. It keeps oil at the correct operating temperature by bypassing the oil cooler during cold starts and routing oil through the cooler once operating temperature is reached. When the thermostat valve fails, oil overheats — triggering high-temperature shutdowns, accelerating wear on compressor components, and causing unplanned downtime. This is an original Ingersoll Rand thermostat control valve, a direct replacement with OEM part number 23425028.
