What are the common classifications of pulse valves?

1. Classification by driving mode
Electromagnetic pulse valve
Features: fast response speed (several milliseconds to tens of milliseconds), simple control, requires power drive, suitable for conventional dust removal systems.
Common types: right-angle type, submerged type, straight-through type.
Right-angle type: the air inlet and the air outlet are at right angles, the air flow turns when passing through, the pressure loss is large, but the structure is compact.
Submerged type: the air inlet is directly embedded in the air bag, the air flow resistance is small, the blowing efficiency is high, and it is widely used in large dust collectors.
Straight-through type: the air inlet and the air outlet are directly connected, the structure is simple, and it is suitable for low-pressure scenes.

Pneumatic pulse valve
Features: no power supply is required, it is controlled by air pressure signal, the explosion-proof performance is good, and it is suitable for flammable and explosive environments (such as chemical industry, coal mines), but the response speed is slightly slower than the electromagnetic type.

2. Classification by structural form
Diaphragm pulse valve: the rubber diaphragm is used as the opening and closing part, with low cost and good sealing, but the diaphragm is easy to age and needs to be replaced regularly.

Piston pulse valve: adopts metal piston structure, has strong pressure resistance and long service life, and is suitable for high pressure (above 0.6MPa) working conditions.

3. Classification by application scenario
Industrial dust removal pulse valve: used for bag dust collectors in power plants, steel, cement and other industries, with large dust handling capacity.
Environmental protection equipment pulse valve: suitable for small dust removal equipment or mobile environmental protection devices, with small specifications and flexible installation.
