Atlas Copco 3001531150

I. Core Functions and Working Characteristics of Atlas Copco

Precise Temperature Control

This valve uses an internal temperature sensor to monitor the temperature of the medium . When the temperature reaches 55℃, it automatically opens the cooling path; when it is below this temperature, it closes or reduces the cooling flow to ensure that the system temperature remains within the range of approximately 55℃.

It is suitable for scenarios that are sensitive to temperature, avoiding the deterioration of oil quality or the decline in compressed air quality due to excessively high temperatures. Protection mechanism

Compared to conventional temperature control valves , the 55℃ temperature control valve can start cooling earlier, and is suitable for special models or modified systems that require low-temperature operation to prevent component aging due to local overheating.

II. Application Scenarios and Model Matching

Applicable models: Commonly seen in small and medium-sized air compressors or specific customized models , or used in the auxiliary cooling circuits of air compressors .

Model identification: The original Atlas Copco 55℃ temperature control valve has specific spare parts numbers, and it is necessary to distinguish it from conventional temperature setting control valves.

When replacing, it is necessary to confirm the interface size, installation method, and medium flow direction of the valve to ensure compatibility with the original system.

III. Common Faults and Troubleshooting

Valve Stuck

Symptoms: Unable to open when the temperature reaches 55℃ , or unable to close when the temperature is below 55℃.

Reasons: Accumulation of oil and impurities or aging of the temperature sensing element. Clean the valve core after disassembly and repair if ineffective; replace the valve if necessary.

Temperature Response Deviation

The actual opening temperature is too far from 55℃ , which may indicate failure of the temperature sensing element. Replace the valve.

Leakage

Damage to the valve body or sealing components causing medium leakage, affecting cooling efficiency. Replace the sealing components or the entire valve.

IV. Replacement and Maintenance Tips

Replacement Timing

When the system temperature continuously deviates from the 55℃ range and it is confirmed that it is a fault of the temperature control valve;

When the valve has leakage, stuck, or other unreparable faults;

Replace it when following the recommended preventive maintenance cycle of the equipment manual.

Installation Precautions

Select the original 55℃ dedicated temperature control valve to ensure the accurate temperature setting value;

Clean the pipe interface before installation, remove residual impurities;

Pay attention to the medium flow direction , do not install it in reverse;

After replacement, start the equipment, monitor the temperature changes, and confirm that the valve can operate normally at around 55℃. Daily maintenance

Regularly check for any leakage traces around the valves;

In conjunction with the oil replacement process, clean the oil passages near the temperature control valve to remove impurities and prevent sticking.
