Alstom OptiPow 105 V1617803 is a compact piston-type pulse cleaning valve designed for pulse jet dust collector systems, especially Alstom Optipulse fabric filter units. The model number V1617803 refers to the complete OptiPow 105 valve assembly, with V1617803-0100 being the common 24V DC solenoid version.
What does Alstom OptiPow 105 V1617803 Valve do?
The OptiPow 105 valve controls the release of compressed air pulses into the filter bags of a dust collector. When activated by the cleaning controller, the valve opens rapidly and releases a powerful burst of compressed air, removing dust buildup from the filter bags and maintaining stable airflow.
Unlike traditional diaphragm pulse valves, the OptiPow series uses a piston/plunger design, which provides fast response and efficient air cleaning performance. The “105” designation refers to the piston diameter size.
How does the OptiPow 105 V1617803 work?
The operating process is:
- Standby condition
- Compressed air enters the valve chamber.
- The internal plunger remains closed, sealing the compressed air outlet.
- Electrical activation
- The solenoid valve receives a signal from the dust collector controller.
- The pilot air pressure is released.
- Rapid opening
- Pressure imbalance moves the internal plunger upward.
- A high-pressure air pulse is discharged into the blow pipe.
- Filter cleaning
- The compressed air pulse expands through the filter bags.
- Dust particles are shaken off and fall into the hopper.
- Reset
- The pilot valve closes.
- Pressure equalizes and the plunger returns to the closed position.
Main Features of Alstom OptiPow 105 V1617803
1. Compact piston design
The OptiPow valve is smaller than conventional diaphragm pulse valves, allowing closer filter bag spacing and more compact dust collector designs.
2. High cleaning efficiency
The piston structure provides:
- Fast opening response
- Strong pulse pressure
- Lower compressed air consumption
3. High-temperature industrial application
The valve is commonly used in industries such as:
- Power plants
- Cement production
- Steel and metallurgy
- Glass manufacturing
- Mining
- Industrial dust collection systems
