Submerged Pulse Valve Technical Guide
1. What is a Submerged Pulse Valve?
The submerged pulse valve is specifically designed to be installed directly inside the air manifold (tank). By being “immersed,” it eliminates intake piping, providing a direct airflow path for maximum cleaning efficiency.
2. Working Principle
Operation is based on pressure differentials. When the solenoid pilot is energized, it exhausts air from the rear chamber. This causes the diaphragm to lift instantly, allowing the air from the tank to pulse into the blowpipe with zero resistance.
3. Key Advantages
- Energy Saving: Delivers high-impact cleaning at low pressure (0.2–0.4 MPa).
- Long Bag Specialist: Ideal for filter bags exceeding 6 meters in length.
- Anti-Icing: Manifold mounting prevents the valve from freezing in cold climates.
4. Maintenance Considerations
While the submerged design requires the air manifold to be depressurized for maintenance, its high-reliability diaphragms (tested for 1 million+ cycles) ensure long-term, low-intervention operation.
5. Primary Applications
Widely utilized in Thermal Power Plants, Cement & Mining industries, and Metallurgy for large-scale baghouse filtration and high-concentration emission control.
