Atlas Copco 1614897300 Oil Stop Valve Piston

The Atlas Copco Oil Stop Valve Piston 1614897300 serves as a critical control component in oil-injected screw air compressors. The piston operates inside the oil cut-off valve assembly and regulates lubricant circulation during compressor start-up and shutdown. As a result, the system maintains stable oil supply to the airend while preventing oil backflow after shutdown. Engineers designed this component for demanding industrial environments that require stable lubrication and reliable sealing performance. In addition, the piston combines precision-machined metal materials with high-temperature sealing components to support long-term operation under high pressure and elevated temperatures. Many Atlas Copco GA series compressors use this component to improve operational stability, lubrication efficiency, and equipment reliability.

The piston then moves into the operating position and aligns the oil passage openings with the internal oil circuit. Consequently, lubricating oil flows continuously into the compressor airend and supports cooling and lubrication of the rotor and bearing system. Compressor Shutdown Operation When the compressor stops, the control pressure disappears and the internal spring immediately pushes the piston back to its original position. The piston then closes the oil passage and blocks residual pressure inside the oil separator tank from forcing lubricating oil back into the airend or intake system. Therefore, the system reduces oil spraying and protects internal compressor components during shutdown conditions. Technical Specifications Item Specification Part Number 1614897300 Product Name Oil Stop Valve Piston Alternative Name Oil Cut-off Valve Core Brand Atlas Copco Application Type Oil-injected Screw Air Compressor Main Material High-strength Alloy Steel / Hardened Aluminum Alloy Seal Material FKM (Viton) Temperature Resistance -20°C to 200°C Compatible Compressor Series GA37 / GA45 / GA55 / GA75 / GA90 Length 14 cm Width 7 cm Height 7 cm Weight 1020 g Material and Sealing Characteristics Manufacturers produce the piston body from high-quality alloy steel or hardened aluminum alloy materials. Furthermore, precision grinding and specialized surface treatment improve wear resistance, dimensional stability, and low-friction performance during continuous operation. The sealing components typically use FKM (Viton) material because it resists compressor oil, oxidation, and thermal aging. In addition, the sealing system maintains stable elasticity and sealing performance even during long-term exposure to high temperatures and high-pressure oil circulation environments. Precision machining creates accurate tolerances between the piston and valve housing. As a result, the piston moves smoothly, minimizes internal leakage, and supports reliable long-term compressor operation. Compatible Compressor Models The Atlas Copco Oil Stop Valve Piston 1614897300 commonly supports medium and large power oil-injected screw air compressors within the Atlas Copco GA series. GA37 GA45 GA55 GA75 GA90 However, actual compatibility may vary according to compressor generation, production batch, and valve block configuration. Therefore, users should verify the part number and equipment manual before installation. Atlas Copco 1614897300 Oil Stop Valve Piston (2) Industrial Applications Industrial manufacturing plants Continuous compressed air systems Heavy-duty screw compressor stations High-temperature operating environments Centralized air supply systems Oil circulation and lubrication control systems Industrial machinery that requires stable compressed air operation Maintenance Recommendations Recommended Service Interval For preventive maintenance, operators should inspect or replace the oil stop valve piston after approximately 8000 operating hours or every 2 to 3 years. However, actual service intervals may vary depending on operating conditions, oil quality, and maintenance schedules. Common Failure Symptoms Oil discharge from the intake valve during shutdown Oil backflow into the airend after compressor stop Insufficient lubrication during compressor start-up Abnormally high airend temperature alarms Valve sticking caused by wear or contamination Seal deterioration that results in internal leakage Installation Notes Technicians should thoroughly clean the valve chamber before installation to remove carbon deposits, metal particles, and oil contamination. In addition, they should apply a small amount of compressor lubricant during assembly to improve installation smoothness and protect the sealing components. Finally, maintenance personnel should avoid scratching the piston surface or damaging the seals during installation. Atlas Copco 1614897300 Oil Stop Valve Piston (3) Conclusion The Atlas Copco Oil Stop Valve Piston 1614897300 plays an essential role in compressor oil circulation control systems. Its precise oil shut-off performance, reliable sealing capability, and durable material structure help compressors maintain lubrication stability and operational safety under demanding industrial conditions. Proper maintenance and timely replacement of the oil stop valve piston can significantly reduce shutdown-related oil discharge issues. Moreover, regular inspection helps improve system reliability and extends the service life of screw air compressor equipment. Frequently Asked Questions What is the function of the oil stop valve piston in a screw air compressor? The oil stop valve piston controls the opening and closing of the oil circulation path inside the compressor system. During operation, it regulates the flow of lubricating oil to the airend, and it also ensures that the system stops oil flow immediately during shutdown. As a result, the compressor maintains stable lubrication while preventing oil backflow and oil leakage into the intake system. What happens if the oil stop valve piston fails? If the oil stop valve piston fails, the compressor may experience several operational issues. For example, oil can flow back into the airend after shutdown, or the intake system may discharge oil during stopping. In addition, the compressor may suffer from insufficient lubrication during start-up, which can lead to high operating temperatures and potential system alarms. Therefore, timely replacement is essential to maintain stable performance. Which Atlas Copco compressors are compatible with part number 1614897300? This oil stop valve piston is commonly used in selected Atlas Copco GA series screw air compressors. In particular, it is suitable for models such as GA37, GA45, GA55, GA75, and GA90. However, because configurations may vary between production batches and system designs, we always recommend verifying compatibility through the equipment manual or part number confirmation before installation. How often should the oil stop valve piston be replaced? Under normal operating conditions, technicians typically recommend replacing the oil stop valve piston every 8000 operating hours or every 2 to 3 years. However, maintenance intervals may vary depending on oil quality, load conditions, and working environment. Therefore, regular inspection helps ensure optimal performance and reduces unexpected system failures. What material is used for the sealing components of this piston? Manufacturers use FKM (Viton) as the primary sealing material for this piston. This material provides excellent resistance to high temperatures, compressor oil, and long-term thermal aging. In addition, it maintains stable elasticity under continuous pressure, which helps ensure reliable sealing performance throughout the service life of the component. Can improper installation affect compressor performance? Yes, improper installation can significantly affect compressor performance. For instance, if the piston surface becomes scratched or if the sealing components are damaged during installation, the system may develop internal leakage or unstable oil control. Therefore, technicians should clean the valve chamber thoroughly, apply proper lubrication during assembly, and carefully follow installation procedures to ensure correct operation.
