A pulse jet valve, also commonly called a diaphragm pulse valve or electromagnetic pulse valve, is an important pneumatic component used in pulse-jet cleaning systems.
In a typical dust collection system, compressed air is stored in an air tank or gas bag. When the controller sends an electrical signal to the solenoid, the pulse valve opens rapidly and releases a short, powerful burst of compressed air into the blowing pipe.
This pulse of compressed air is used to clean accumulated dust from filter bags or filter cartridges.
The installation diagram of the YDA series shows a typical configuration consisting of the electromagnetic pulse valve, gas bag, blowing pipe, coupling connector and fitting coupler.
For an efficient dust collector system, selecting the correct pulse valve is important because the valve must provide sufficient airflow while matching the pipe size, operating pressure and cleaning requirements of the system.
The YDA-Z series includes several sizes designed for different airflow and dust collector requirements.
Available models include:
Model | Diaphragm Diameter | Flow Coefficient Kv/Cv | Injection Area | Port Size |
|---|---|---|---|---|
YDA-Z-20 | 80 mm | 17.55 / 20.48 | 3.5–6 m² | G 3/4" |
YDA-Z-25 | 96 mm | 26.16 / 30.53 | 8–10 m² | G 1" |
YDA-Z-40S | 112 mm | 45.82 / 53.47 | 12–16 m² | G 1-1/2" |
YDA-Z-50S | 160 mm | 61.24 / 71.47 | 18–28 m² | G 2" |
YDA-Z-62S | 188 mm | 129.26 / 150.85 | 27–38 m² | G 2-1/2" |
Correct air pressure is essential for reliable pulse cleaning.
For the YDA series:
Z right-angle type: 0.3–0.8 MPa
Y submerged type: 0.2–0.6 MPa
The compressed-air supply should remain within the recommended pressure range to achieve stable valve operation.
The recommended working medium is:
Dry and clean compressed air.
Clean compressed air helps reduce contamination inside the pilot and diaphragm mechanism.
When pulse valves are installed in industrial dust collection equipment, proper air preparation can therefore contribute to more stable operation and reduced maintenance requirements.
The specified working temperature range is:
-5°C to +80°C
When selecting a pulse valve, buyers should check not only the ambient temperature but also the operating conditions around the dust collector and compressed-air system.
Standard electrical options include:
AC 220V
DC 24V
Special voltages are also available as optional configurations.
DC24V is commonly selected for industrial control systems, while voltage selection should always match the pulse controller or control cabinet used in the dust collector.
The specified diaphragm life for the YDA series is:
Over one million cycles.
Because pulse valves repeatedly open and close during filter cleaning, diaphragm durability is an important consideration for continuous industrial operation.
Choosing a pulse valve based only on price can result in poor dust-cleaning performance or unnecessary system cost.
Several parameters should be considered.
The first step is to check the pipe or valve connection size.
For example:
G3/4" → YDA-Z-20
G1" → YDA-Z-25
G1-1/2" → YDA-Z-40S
G2" → YDA-Z-50S
G2-1/2" → YDA-Z-62S
This makes port size one of the easiest ways to narrow down the correct pulse valve model.
The different models are designed for different injection areas.
For smaller cleaning areas, the YDA-Z-20 or YDA-Z-25 may be sufficient.
For larger dust collection systems, higher-flow models such as the YDA-Z-50S or YDA-Z-62S may be more appropriate.
For example, the YDA-Z-62S has a specified injection area of 27–38 m² and a G2-1/2" port, while the smaller YDA-Z-20 covers 3.5–6 m² with a G3/4" connection.
Pulse cleaning requires a large volume of compressed air to be released within a very short period.
For this reason, the Kv/Cv flow coefficient is another useful selection parameter.
The YDA-Z series ranges from:
17.55 / 20.48 Kv/Cv for the YDA-Z-20
up to:
129.26 / 150.85 Kv/Cv for the YDA-Z-62S.
Generally, a larger valve and diaphragm provide greater airflow capacity for larger cleaning systems.
The ordering information for this series identifies two configurations:
Z – Right-angle type
Y – Submerged type
A right-angle pulse valve connects the compressed-air tank and blowing pipe through a 90-degree flow path.
This configuration is widely used where convenient piping and straightforward maintenance are important.
A submerged pulse valve is installed directly into or closely integrated with the compressed-air manifold.
This arrangement can provide a compact installation and a shorter airflow path.
When replacing an existing pulse valve, buyers should confirm the installation structure before ordering because right-angle and submerged valves are not interchangeable simply based on port diameter.
The pulse valve directly affects the compressed-air pulse delivered to the filter elements.
An undersized valve may not provide enough airflow for effective cleaning.
An oversized valve, on the other hand, may increase compressed-air consumption and system cost without delivering a meaningful improvement.
For this reason, engineers and purchasing teams should consider the complete system instead of selecting the valve based on thread size alone.
Important information includes:
Pulse valve port size
Filter bag or cartridge quantity
Cleaning area
Air tank pressure
Blowing pipe diameter
Valve quantity
Required pulse airflow
Coil voltage
Installation type
Operating temperature
Providing these details to the valve supplier can significantly improve model selection accuracy.
Diaphragm pulse jet valves are commonly used as part of pulse-cleaning equipment in industrial dust collection systems.
Typical application environments can include:
Baghouse dust collectors
Cartridge dust collectors
Industrial filtration systems
Powder processing equipment
Cement production equipment
Metalworking dust collection
Woodworking dust extraction
Mining and bulk-material handling systems
Chemical and powder processing plants
The exact valve size should be selected according to the dust collector design and compressed-air requirements.
To receive an accurate quotation for a pulse jet valve, it is helpful to provide the following information:
1. Connection size
For example: G1", G1-1/2", G2" or G2-1/2".
2. Valve structure
Right-angle or submerged type.
3. Coil voltage
For example: DC24V or AC220V.
4. Working pressure
Specify the compressed-air pressure used in your system.
5. Required quantity
6. Existing valve model or photos
If the valve is being used as a replacement, send clear photos of the valve, nameplate and connection.
7. Dust collector information
For new projects, provide the cleaning area, number of filter bags or cartridges and relevant piping information.
These details allow the supplier to recommend a more suitable model instead of simply matching the valve by appearance.
For fast selection, the YDA-Z series can be summarized as follows:
YDA-Z-20
G3/4" connection, 80 mm diaphragm, suitable for smaller cleaning areas.
YDA-Z-25
G1" connection, 96 mm diaphragm and increased flow capacity.
YDA-Z-40S
G1-1/2" connection, 112 mm diaphragm and 12–16 m² specified injection area.
YDA-Z-50S
G2" connection, 160 mm diaphragm and 18–28 m² specified injection area.
YDA-Z-62S
G2-1/2" connection, 188 mm diaphragm and the highest flow capacity within this product range.
The product datasheet also specifies relative air humidity below 85% and an operating temperature range of -5°C to +80°C.
A reliable pulse jet cleaning system starts with correct valve selection.
Instead of choosing a diaphragm pulse valve based only on connection size, buyers should evaluate airflow capacity, diaphragm diameter, cleaning area, working pressure, voltage and installation structure together.
The YDA-Z pulse valve range covers port sizes from G3/4" to G2-1/2", offering multiple flow capacities for different dust collector configurations.
