Diaphragm Pulse Valve

A diaphragm pulse valve is a core pneumatic control valve specially designed for pulse jet dust cleaning systems.Driven by electromagnetic signals,it relies on the quick opening and closing of a rubber diaphragm to release instantaneous high-pressure compressed air pulses.It is widely installed in baghouse dust collectors and cartridge dust removal equipment,and is the most commonly used pulse valve in industrial environmental protection.

Working Principle

The whole valve adopts pilot-operated diaphragm structure.In normal closed condition,air pressure balances on both sides of the diaphragm,keeping the valve tightly sealed.

When the solenoid coil receives an electric pulse signal,the pilot valve opens instantly,releasing the air pressure in the upper control chamber.At this time,the pressure difference between front and back pushes the main diaphragm to open rapidly,and a strong compressed air jet is ejected in a very short time to clean dust attached on filter bags.

After the electrical signal disappears,the pilot hole closes,the upper chamber restores air pressure,and the diaphragm resets quickly to close the air passage.The entire opening and closing process is completed within milliseconds.

Main Features

Rapid response speed

Ultra-fast opening and closing action,stable high-frequency continuous operation,strong pulse jet strength and excellent dust removal effect.

Excellent diaphragm durability

Adopt high-quality special rubber diaphragm with good elasticity,wear resistance,aging resistance and long service life.

Good airtight performance

No air leakage under closed state,low air consumption,effectively saving compressed air resources.

Stable and reliable structure

The valve body is mostly die-cast aluminum alloy with light weight,high structural strength and corrosion resistance.

Wide voltage adaptation

Support multiple common industrial voltage specifications:DC24V,AC110V,AC220V,suitable for most global dust collector control systems.

Common Types

Right angle diaphragm pulse valve

Most universal type,inlet and outlet at 90 degrees,easy installation and wide application.

Submerged diaphragm pulse valve

Embedded installed in air bag,small air pressure loss,stronger jet power.

Straight through diaphragm pulse valve

Inline pipeline connection,suitable for special large-flow dust removal pipelines.

Applications

It is extensively applied in all kinds of industrial dust removal fields,including cement plants,metallurgy,mining,woodworking,furniture manufacturing,food processing,pharmaceutical industry,power plants,chemical industry and foundry workshops.

It efficiently clears dust cake accumulated on filter bags and filter cartridges,maintains good ventilation of filtration system,prolongs service life of filter materials and ensures stable operation of environmental protection equipment.
