Alstom Optipow 105 air cleaning valve is a high-performance 3-inch pulse jet valve designed with moving plunger for cleaning filter bags in industrial dust collection systems. It uses a short burst of compressed air to remove dust particles from the surface of filter bags, helping maintain efficient filtration performance and reduce pressure drop.
The Optipow 105 valve was developed for Alstom Optipulse fabric filters and is known for its compact design, fast response, high cleaning efficiency, and reliable operation in demanding industrial environments.
How Does an Alstom Optipow 105 Valve Work?
The Alstom Optipow 105 is a piston-type pulse cleaning valve that operates by controlling compressed air flow from a pressure tank to the filter bags.
The working process includes:
1. Standby Condition
During normal operation, compressed air is stored inside the air reservoir. The valve remains closed, preventing air leakage.
2. Electrical Pulse Signal
When the dust collector controller sends an electrical signal, the solenoid valve activates and releases pilot air pressure.
3. Rapid Valve Opening
The pressure balance inside the valve changes, allowing the internal plunger to move quickly and open the main air passage.
4. Compressed Air Cleaning Pulse
A powerful compressed air pulse is released through the blow pipe into the filter bags. The sudden expansion of air causes the filter bags to flex, removing accumulated dust from the outer surface.
5. Valve Closing
After the pulse signal ends, the valve quickly closes and prepares for the next cleaning cycle.
Main Features of Optipow 105 Air Cleaning Valve
Compact Piston Design
Unlike traditional diaphragm pulse valves, the Optipow 105 uses a compact piston/plunger structure. The smaller size allows closer valve installation spacing and more flexible filter design.
High Cleaning Efficiency
The valve provides a fast and powerful air pulse, improving dust removal efficiency while reducing compressed air consumption.
Strong Durability
The Optipow 105 is designed for industrial applications and can operate with compressed air pressure up to approximately 6 bar (600 kPa) under normal conditions.
Easy Maintenance
The modular design makes inspection and replacement of internal components, such as seals, plungers, and solenoid valves, easier.
