When selecting a pulse cleaning valve for an industrial dust collector, you may come across two well-known OPTIPOW models: OPTIPOW 105 and OPTIPOW 135.
Both valves are designed for pulse-jet cleaning of fabric filters and use a piston-based operating mechanism to release compressed air into the cleaning pipe. The main difference is the size of the piston: the OPTIPOW 105 has a piston diameter of approximately 105 mm, while the OPTIPOW 135 has a piston diameter of approximately 135 mm.
Understanding this difference is important when selecting a replacement valve, checking spare parts, or designing a dust collection system.
What Is an OPTIPOW Pulse Valve?
An OPTIPOW valve is a compact, fast-acting pulse cleaning valve used in industrial dust collection systems.
The valve is installed on a compressed-air pressure tank and connected to a blow tube. When the cleaning controller sends a signal to the pilot solenoid valve, the pilot air circuit changes the pressure balance inside the valve.
The piston then moves rapidly, opening the main air passage. A short burst of compressed air is released through the blow tube and into the filter bags.
This pulse creates a reverse-airflow effect that removes accumulated dust from the filter media.
After the cleaning pulse, the piston returns to its closed position and the valve is ready for the next cleaning cycle.
OPTIPOW 105 vs. OPTIPOW 135 at a Glance
The most important difference can be summarized as follows:
| Feature | OPTIPOW 105 | OPTIPOW 135 |
|---|---|---|
| Valve type | Piston-type pulse cleaning valve | Piston-type pulse cleaning valve |
| Piston diameter | Approx. 105 mm | Approx. 135 mm |
| Typical series | V1617803 | V1614718 |
| Example 24 V version | V1617803-0100 | V1614718-0100 |
| Without solenoid | V1617803-0800 | V1614718-0800 |
| Plunger | V3630527-0100 | V3629022-0100 |
| Membrane | V4549902-0100 | V4549902-0100 |
| Main application | Pulse-jet filter cleaning | Pulse-jet filter cleaning |
The published parts lists show different plunger and sealing configurations for the two valve sizes, while the V4549902-0100 membrane is listed for both OPTIPOW 105 and OPTIPOW 135.
1. The Main Difference: Piston Diameter
The number in the OPTIPOW model name is an important identification feature.
OPTIPOW 105 = approximately 105 mm piston diameter
OPTIPOW 135 = approximately 135 mm piston diameter
The larger piston of the OPTIPOW 135 is associated with a larger valve configuration and different internal components.
This does not mean that OPTIPOW 135 is automatically “better” than OPTIPOW 105. Instead, the correct model depends on the original dust collector design, pressure tank, cleaning system, blow tube arrangement, and required cleaning performance.
2. OPTIPOW 105
The OPTIPOW 105 is a compact piston pulse valve designed for pulse-jet cleaning of fabric filters.
Common valve identification numbers include:
- V1617803-0100 – 24 VDC version
- V1617803-0200 – 110 V/60 Hz or 100 V/50/60 Hz version
- V1617803-0300 – 110 V/50 Hz version
- V1617803-0400 – 120 V/60 Hz version
- V1617803-0500 – 220 V/50 Hz version
- V1617803-0800 – version without solenoid and with 90° revolving configuration
These variations show why the complete part number should be checked rather than identifying a valve only as “OPTIPOW 105.”
The OPTIPOW 105 also has its own specific internal components, including the V3630527-0100 plunger.
3. OPTIPOW 135
The OPTIPOW 135 is the larger piston configuration in the OPTIPOW family.
Common identification numbers include:
- V1614718-0100 – 24 V version
- V1614718-0301 – 100 V/50 Hz version
- V1614718-0400 – 120 V/60 Hz version
- V1614718-0700 – 120 V/60 Hz UL-certified version
- V1614718-0800 – version without solenoid and with 90° revolving configuration
The OPTIPOW 135 uses the V3629022-0100 plunger, which is different from the plunger used in the OPTIPOW 105.
4. Are the OPTIPOW 105 and 135 Parts Interchangeable?
Not all parts are interchangeable.
This is one of the most important points when purchasing replacement components.
For example:
OPTIPOW 105 plunger:
V3630527-0100
OPTIPOW 135 plunger:
V3629022-0100
These are different components designed for their respective valve configurations.
However, some components may be shared between the two models. For example, the V4549902-0100 membrane is listed for both OPTIPOW 105 and OPTIPOW 135.
Therefore, you should always verify the part number before ordering a replacement plunger, O-ring, rubber disc, or other internal component.
5. OPTIPOW 105 vs. OPTIPOW 135: Which One Has a Stronger Cleaning Pulse?
It is tempting to assume that the larger OPTIPOW 135 will always provide better filter cleaning.
However, valve selection should not be based on piston diameter alone.
The actual cleaning performance depends on the complete pulse-jet system, including:
- Compressed-air pressure
- Pressure tank volume
- Blow tube design
- Blow tube orifice arrangement
- Filter bag dimensions
- Filter media
- Dust characteristics
- Valve configuration
- Pulse duration
- Cleaning frequency
A correctly designed OPTIPOW 105 system can perform better than an incorrectly configured larger valve.
For this reason, OPTIPOW 105 and OPTIPOW 135 should be considered different configurations rather than simply “small” and “large” versions of the same valve.
6. OPTIPOW 105 vs. OPTIPOW 135 for Dust Collectors
Both models are designed for industrial fabric-filter cleaning applications.
They can be found in dust collection systems associated with industries such as:
- Power generation
- Cement manufacturing
- Steel production
- Mining
- Metallurgy
- Glass manufacturing
- Chemical processing
- Industrial manufacturing
The valve releases compressed air into the blow tube, helping remove dust from filter bags and maintain effective filtration.
The correct model depends on the original system design.
7. How to Choose Between OPTIPOW 105 and 135
If you are replacing an existing OPTIPOW valve, the safest approach is to identify the original valve rather than selecting a model based only on appearance.
Check the following information:
Check the Valve Model
Look for markings such as:
OPTIPOW 105
or
OPTIPOW 135
Check the Article Number
For example:
V1617803-0100 indicates an OPTIPOW 105 configuration.
V1614718-0100 indicates an OPTIPOW 135 configuration.
The suffix is also important because it can indicate different solenoid-voltage or valve configurations.
Check the Plunger
If the valve has been disassembled, check the plunger identification.
OPTIPOW 105:
V3630527-0100
OPTIPOW 135:
V3629022-0100
Check the Solenoid
Different electrical versions are available, including 24 VDC and various AC voltage/frequency configurations. Therefore, the solenoid voltage should be confirmed before ordering a complete valve.
8. Can You Replace OPTIPOW 105 with OPTIPOW 135?
A direct replacement should not be assumed.
Although both valves perform the same general function, their piston dimensions and some internal components are different.
Before replacing an OPTIPOW 105 with an OPTIPOW 135, check:
- Pressure tank connection
- Valve dimensions
- Blow tube arrangement
- Pulse cleaning requirements
- Compressed-air supply
- Filter bag configuration
- Valve spacing
- Solenoid specifications
- Original equipment design
For an existing dust collector, replacing the valve with the same model and configuration is generally the simplest approach.
If a different model is being considered, the complete cleaning system should be evaluated first.
9. OPTIPOW Spare Parts: What Should You Keep in Stock?
For plants operating a large number of pulse valves, keeping critical spare parts available can help reduce maintenance downtime.
Common OPTIPOW spare parts include:
- Plunger
- Membrane
- O-rings
- Rubber disc
- Pilot cover
- Plate
- Coupling set
- Solenoid valve
For OPTIPOW 105, the V3630527-0100 plunger is an important model-specific component.
For OPTIPOW 135, the corresponding plunger is V3629022-0100.
The V4549902-0100 membrane is listed for both models, making it an example of a component that can be common across the two configurations.
10. Final Comparison
The difference between OPTIPOW 105 and OPTIPOW 135 can be summarized simply:
OPTIPOW 105 uses an approximately 105 mm piston and belongs to the V1617803 series.
OPTIPOW 135 uses an approximately 135 mm piston and belongs to the V1614718 series.
Both are piston-type pulse cleaning valves designed for industrial dust collection systems, but they should not be treated as universally interchangeable.
When selecting a replacement valve, always check the complete article number, piston/plunger specification, solenoid voltage, connection arrangement, and dust collector design.
Choosing the correct OPTIPOW configuration can help maintain reliable pulse cleaning, reduce filter pressure drop, and minimize unnecessary maintenance and downtime.
Conclusion
The OPTIPOW 105 and OPTIPOW 135 are two important configurations of the OPTIPOW piston pulse valve family.
The key difference is the piston diameter, but the differences extend to model-specific plungers and other internal components. OPTIPOW 105 commonly uses the V1617803 series, while OPTIPOW 135 commonly uses the V1614718 series.
If you are purchasing a replacement valve or spare parts, do not select the product based on the model name alone. Confirm the original part number and component number to ensure the replacement is compatible with your existing dust collector system.
