The Atlas Copco 2202815906 automatic drain valve is a premium condensate management component used in screw compressor systems where efficient removal of moisture and oil-contaminated condensate is essential for maintaining air quality and system stability. This model focuses on delivering consistent, long-cycle operation, even in conditions where condensate carries a significant amount of emulsified oil, rust flakes, and temperature-induced impurities.
Its internal actuation system operates automatically through pressure fluctuations inside the drainage chamber. This ensures that the compressor remains free of standing water, prevents corrosion in downstream components, and supports stable pressure delivery during load–unload transitions.
Compared with standard drain designs, this model adopts a more robust sealing structure, improved throttling components, and a smoother discharge path engineered for minimal clogging and reduced maintenance.
Key Features
1. Enhanced Sealing Design for Zero-Leakage Performance
The 2202815906 valve incorporates an upgraded sealing interface that withstands rapid pressure cycles and resists the chemical effects of compressor lubricants. Its strengthened O-rings and sealing groove geometry reduce the risk of micro-leakage over extended use, ensuring consistent draining performance without energy loss.
2. Optimized Internal Throttling Assembly
A precision-machined throttling component inside the valve regulates the flow rate of condensate during discharge. This stabilizes the opening/closing movement of the valve, enabling softer actuation without sudden pressure drops. The result is smoother operation, quieter cycles, and improved durability of moving elements.
3. Superior Oil–Water Handling Capability
The internal drainage passages are treated with anti-adhesion surface technology that minimizes residue buildup from oil-rich condensate. This significantly reduces clogging frequency and allows the system to maintain reliable discharge performance even when the compressor is operating under heavy load or in high-humidity factory environments.
4. Stable Operation During Long Duty Cycles
Unlike basic mechanical drains, this model is engineered to function continuously for long shifts without requiring manual resets. Internal components are resistant to fatigue, heat variation, and repeated pressure impacts—making it ideal for industrial plants that run 16–24 hours per day.
5. Robust Construction for Industrial Conditions
The housing is made of corrosion-resistant metal alloy with high mechanical strength, ensuring that the valve maintains dimensional stability over years of operation. Chemical-resistant elastomers further enhance lifespan when exposed to acidic condensate or high-temperature lubricant vapors.
Working Principle
During compressor operation, moisture and oil vapor condense into a mixture inside the tank or separator. When internal pressure reaches the preset threshold:
- The valve senses the pressure imbalance
- The actuator triggers the opening sequence
- Condensate is discharged through the enlarged flow path
- The valve closes firmly once the pressure equalizes
This automatic cycle prevents water accumulation, protects filters and dryers, and reduces corrosion across the air system.
Performance Benefits
- Cleaner Air System
Removes harmful moisture to protect pipelines, downstream valves, regulators, and pneumatic equipment. - More Efficient Compressor Operation
Minimizes air leakage during draining, supporting stable pressure output and reducing unnecessary energy consumption. - Lower Maintenance Frequency
Anti-clogging design and oil-resistant materials significantly reduce the need for manual cleaning. - Better Protection for Separator & Filter Components
Consistent draining prevents excessive load on oil–air separators and coalescing filters.
Quality Assurance & Testing
Each 2202815906 drain valve undergoes strict testing procedures such as:
- Pressure endurance test
- Leak-tightness verification
- Oil-contaminated condensate compatibility test
- Flow performance evaluation
- Actuation response accuracy test
Only products that meet OEM-level standards are released.
