The Atlas Copco shut-off valve 2205261001 is an essential safety and flow-control component used to isolate the air circuit during maintenance, startup procedures, or emergency shutdowns. Designed to perform under fluctuating pressure conditions, this valve provides highly stable sealing performance, preventing unwanted air leakage and ensuring the compressor operates smoothly within its intended pressures and load cycles.
This model is engineered for durability in heavy-duty industrial environments, offering dependable performance in continuous-operation scenarios such as manufacturing lines, workshops, mining facilities, and energy plants.
Key Features
1. Secure Airflow Isolation
The primary function of this shut-off valve is to quickly and completely block airflow when required. Its internal mechanism is designed to respond with minimal delay, ensuring that technicians can safely conduct inspections or component replacements without residual air pressure entering the system.
2. High-Precision Machined Body
The valve body is manufactured using high-strength alloy materials and processed through advanced CNC machining. This guarantees tight dimensional tolerance, smooth internal channels, and excellent resistance to deformation even under prolonged high-pressure exposure.
3. Optimized Sealing Structure
A multi-layer sealing design—combining elastomer rings, polished sealing seats, and a reinforced closure plate—minimizes the risk of leakage. The sealing components are prepared to withstand lubricant vapors, high-temperature compressed air, and mechanical vibration.
4. Stable Operation in High-Load Systems
The 2205261001 shut-off valve remains stable under rapid load changes and fluctuating airflow. The internal flow path is optimized to reduce turbulence, maintaining reliable operation even during high-capacity compressor cycles.
5. Corrosion-Resistant Surface Treatment
To enhance service life, the valve exterior undergoes anti-corrosion surface treatment, protecting against moisture, oil contamination, and long-term oxidation—especially valuable in humid or dusty worksites.
Manufacturing & Quality Control
To ensure long-term reliability and consistency, each valve is manufactured under strict quality management processes:
- Pressure endurance testing for maximum rated pressure
- Leakage testing under hot and cold conditions
- Valve closing speed test to confirm quick response
- Material hardness and coating adhesion inspection
- Dimensional accuracy validation using precision gauges
Every unit is batch-tracked for traceability, guaranteeing stable and repeatable performance.
Functional Role in Atlas Copco Compressor Systems
- System Protection
During maintenance or system shutdown, the valve prevents backflow and isolates critical components from residual air pressure, protecting the separator tank, pressure lines, and downstream equipment. - Operational Safety
By ensuring clean and instant isolation, it helps technicians work safely, reducing the risk of accidental air discharge or sudden pressure surges. - Performance Stability
A properly functioning shut-off valve helps maintain correct start-stop control, reduces unnecessary air losses, and supports the compressor’s overall energy efficiency.
