The 1619533201 pressure regulator plays a vital role in maintaining stable system pressure and ensuring the efficient operation of Atlas Copco screw compressors. It automatically adjusts discharge airflow during load and unload cycles, optimizing system efficiency while preventing overpressure or sudden pressure drops.
This model is specifically engineered for compressors that demand tight pressure regulation with rapid response times, such as those operating in high-cycling or variable-load environments. Its advanced pilot valve structure delivers exceptional sensitivity and consistency, allowing the compressor to maintain a smooth and balanced air output curve even under fluctuating workloads.
Engineering Design and Construction
Each 1619533201 unit is manufactured with precision engineering and durable material selection to meet the demanding requirements of continuous compressor operation.
Key technical features include:
- Valve Body: Constructed from anodized aluminum alloy, ensuring a lightweight yet durable housing with excellent resistance to corrosion and heat.
- Valve Core & Seat: Made from precision-ground stainless steel (SUS304), delivering excellent dimensional stability and wear resistance.
- Dynamic Diaphragm System: A reinforced elastomer diaphragm designed for high-frequency operation, providing quick pressure compensation and maintaining long-term elasticity.
- Sealing Components: The sealing ring adopts PTFE + NBR composite material, capable of withstanding temperature variations from -20°C to 120°C while ensuring zero leakage.
- Pilot Port Design: Streamlined airflow path reduces internal turbulence, improving pressure accuracy and response time.
- Spring Chamber Venting: Optimized vent system minimizes backpressure buildup and enhances regulator stability.
This comprehensive structural optimization ensures smooth airflow regulation and extended service intervals even in challenging conditions.
Functional Characteristics
The 1619533201 pressure regulator operates through a balanced diaphragm control mechanism, modulating airflow according to real-time system pressure feedback.
Operating stages:
- Load Control: When system pressure drops below the set threshold, the diaphragm drives the valve to open, increasing discharge flow.
- Pressure Stabilization: The regulator modulates airflow dynamically, maintaining a consistent outlet pressure within ±0.015 MPa.
- Unload Transition: As pressure exceeds the preset range, the regulator smoothly closes the valve, preventing sudden discharge fluctuations.
- Dynamic Response: A low-inertia spring and lightweight diaphragm design ensure response times under 150 milliseconds for most compressor applications.
This rapid and precise control contributes to energy savings, smoother compressor cycles, and reduced mechanical stress on downstream components.
Performance & Benefits
- High Sensitivity: Instantly responds to pressure changes, maintaining precise air output.
- Leak-Free Reliability: Advanced PTFE sealing technology prevents micro-leaks during continuous operation.
- Heat Resistance: Stable performance up to 120°C.
- Corrosion Resistance: Surface-treated components extend service life in humid or oily environments.
- Energy Efficiency: Minimizes idle time and reduces compressor wear.
- Easy Maintenance: Modular internal design allows for easy replacement of the diaphragm and spring assembly.
Testing & Quality Assurance
Every pressure regulator undergoes a series of controlled inspections before shipment to ensure consistent reliability and performance:
- Pressure Accuracy Test: Confirms outlet pressure deviation ≤1.5%.
- Thermal Shock Simulation: Ensures performance stability under rapid temperature shifts.
- Leakage Detection: Helium-based detection guarantees sealing integrity under 13 bar pressure.
- Flow Curve Calibration: Validates linear pressure response under variable flow conditions.
- All testing conforms to ISO air purity standards and quality management requirements.
Installation and Maintenance Notes
- Install the regulator with the airflow direction aligned with the arrow marking on the housing.
- Clean the inlet air path before installation to avoid particulate contamination.
- Periodically inspect diaphragm flexibility and replace sealing components if deformation is detected.
- Use proper torque when tightening connection fittings to prevent microleaks.
- Avoid exposure to strong vibration or corrosive gases to extend service life.
