In Atlas Copco rotary screw compressors, the pressure regulating valve plays a vital role in balancing air system pressure and protecting key components such as the air end, oil separator, and motor from overloading. This valve modulates the internal pressure by adjusting airflow between the compressor’s compression chamber and discharge line, ensuring that the system operates at its ideal working pressure.
The 2252049596 valve is engineered for precise response and durability, providing smooth pressure transitions and eliminating sudden surges or drops. It helps reduce energy consumption by allowing the compressor to maintain steady operation rather than frequently loading and unloading—a key factor in prolonging compressor lifespan and efficiency.
Key Features and Technical Advantages
- OEM-Level Precision
This valve is manufactured according to Atlas Copco’s factory specifications for response sensitivity and pressure range calibration. Its internal spring and piston assembly are fine-tuned for consistent performance and minimal hysteresis. - Corrosion-Resistant Design
The valve body is constructed from nickel-plated aluminum alloy, while internal components are made from stainless steel to withstand oil mist, moisture, and heat from continuous compressor duty cycles. The surfaces are treated with anti-corrosion coatings for extended lifespan even in humid or dusty environments. - Advanced Sealing Technology
A multi-layer sealing structure using PTFE and fluororubber (FKM) provides superior resistance to oil, heat, and pressure. The seals ensure leak-free operation across a wide range of temperature and pressure fluctuations. - Smooth Pressure Control
The valve ensures gradual adjustment during pressure buildup, preventing sudden discharge or backflow that could cause vibration or stress to the air end. This contributes to quieter operation and reduced mechanical wear.
Working Principle
When system pressure exceeds the preset threshold, the spring and piston mechanism partially open the relief path to release excess air pressure. As pressure drops below the setpoint, the valve gradually closes, maintaining a constant operating range. This dynamic feedback control enables smooth load transitions and protects downstream equipment from pressure surges.
The 2252049596 valve’s internal geometry and port design are optimized to reduce flow resistance and turbulence, ensuring fast response without overshoot—an essential feature for high-speed screw compressor systems.
Quality Control & Manufacturing Standards
Each valve undergoes rigorous inspection and functional testing, including:
- Leakage test under 1.6 MPa pressure
- Thermal cycling between -10°C and +120°C
- Flow capacity verification
- Response time calibration within 0.2 seconds
- Endurance testing (100,000+ cycles)
All products are manufactured under ISO quality management systems, ensuring dimensional accuracy, material integrity, and long-term reliability.
Applications
This pressure regulating valve is compatible with a wide range of Atlas Copco rotary screw compressors, especially mid- and large-frame units operating in continuous industrial environments. Typical applications include:
- Manufacturing plants
- Automotive assembly lines
- Petrochemical facilities
- Power generation stations
- General industrial air systems
Maintenance & Replacement Tips
- Inspect valve body and connections for oil or dust contamination every 2000 operating hours.
- Replace seals annually or if leakage is detected under pressure test.
- Avoid high-torque tightening of threads to prevent deformation.
- Ensure proper alignment with the compressor’s pressure line during reinstallation.
- Always recalibrate the valve after replacement using a certified pressure gauge.
