A reliable pulse jet valve is the heart of any efficient dust collection system. The ASCO SCXE353A061 pulse jet valve is a 3-inch submerged (immersion) design widely used in large baghouse applications. This guide provides its specifications, explains the “SCXE” designation, and identifies the correct repair kits—genuine and alternative—to keep your system running.
You will learn exactly which valve you have, which diaphragm kit fits it (C113928), and how to choose between OEM and high-quality replacement parts. Whether you are a procurement specialist or a maintenance engineer, this information ensures you purchase the correct components the first time.
SCXE353A061: Model Number Breakdown
Understanding the ASCO numbering convention helps you verify you have the right valve. The model number contains specific meaning :
- SC: Non-explosion proof (standard construction)
- XE: Submerged (immersion) style valve
- 353: Series number (industry-standard pulse valve platform)
- A: Functional designation
- 061: 3-inch connection size
The “submerged” or “immersion” design means the valve installs directly into the air manifold or header tank. This configuration eliminates external piping, reduces pressure losses, and allows for high-density valve mounting .
Distinguishing Submerged from Angle-Body
ASCO offers two primary pulse valve configurations:
The SCG353A060 is the angle-body equivalent for 3″ applications. The SCXE353A061 is the submerged version, preferred for applications requiring maximum flow efficiency and compact manifold integration.
Technical Specifications
| Parameter | Specification |
|---|---|
| Valve Type | 2/2 way, normally closed, internally piloted |
| Mounting Style | Submerged / Immersion |
| Connection Size | 3 inch (DN80) |
| Body Material | Aluminum die-cast |
| Operating Pressure | 0.35 – 8.5 bar (5 – 123 psi) |
| Ambient Temperature | -20°C to +85°C |
| Standard Seal Material | NBR (nitrile) |
| Coil Insulation Class | F |
| Typical Voltage Options | 24VDC, 24VAC, 110VAC, 220VAC |
The internally piloted design uses differential pressure rather than a mechanical spring to return the diaphragm. This reduces moving parts and eliminates a common failure point .Applications for the SCXE353A061
The 3-inch submerged valve is specified for large-volume dust collection systems where high pulse energy is required :
- Cement production: Baghouses on kilns, clinker coolers, and finish mills
- Power generation: Coal-fired boiler fly ash collection
- Steel manufacturing: Electric arc furnace dust control
- Mining and aggregates: Crusher and screening station dust extraction
- Chemical processing: High-air-volume filtration systems
The submerged design is particularly favored in OEM baghouse panels where space is limited and multiple valves are mounted on a common air header.
Compatible Repair Kits: C113928
When maintenance time comes, the ASCO SCXE353A061 pulse jet valve requires the C113928 diaphragm repair kit .
Kit Contents
A complete C113928 repair kit includes:
- Main diaphragm (rubber membrane)
- Pilot seal disc
- Internal spring
- Gaskets and o-rings
Material Options
| Material | Temperature Range | Best For |
|---|---|---|
| NBR (Nitrile/Buna-N) | -10°C to 70°C | Standard compressed air, oil resistance |
| FKM (Viton) | Up to 180°C | High-temperature applications |
For standard industrial dust collection with ambient compressed air, NBR is appropriate. For applications involving elevated temperatures (above 70°C) or aggressive chemicals, specify the FKM/Viton version.
Alternative Kit Numbers
Depending on the exact valve variant, these alternative ASCO kit numbers may apply:
Always verify your valve nameplate before ordering, as production years may have minor variations.
Genuine vs. Alternative Kits: Buying Advice
We stock both genuine ASCO C113928 kits and high-quality alternatives. Here is how to decide.
Genuine ASCO C113928
Advantages:
- Exact fit and material specification
- Full OEM warranty and traceability
- Required for regulated industries or warranty compliance
Best for: Critical applications, single points of failure, facilities with OEM-only policies.
High-Quality Alternative Kits
Advantages:
- 30-60% cost savings
- Multiple material options (NBR, FKM, EPDM)
- Typically in stock for immediate shipment
Best for: Routine maintenance, budget-conscious operations, plants with many valves.
Selection Guideline
| Condition | Recommendation |
|---|---|
| Standard temp (<70°C), non-critical | Quality alternative (NBR) |
| High temp (>70°C) | Alternative with FKM, or genuine |
| Critical single valve | Genuine ASCO |
| Large annual consumption | Alternative (volume savings) |
| Regulatory requirement | Genuine ASCO |
Installation Overview
Proper installation extends diaphragm life regardless of which kit you choose.
Before installation:
- Depressurize the air tank completely
- Remove the coil and bonnet screws
- Extract old diaphragm assembly
- Inspect the valve body seat for nicks or pitting
- Clean the cavity thoroughly
During installation:
- Install new diaphragm without twisting
- Ensure proper bleed hole orientation (if present)
- Replace pilot seal and spring
- Tighten bonnet screws evenly in crisscross pattern
- Torque to specification (typically 6-8 Nm for 3″ valves)
After installation:
- Pressurize slowly and check for leaks
- Cycle valve several times to verify operation
- Listen for audible leaks from vent port when closed
Signs of Diaphragm Failure
If your SCXE353A061 exhibits any of these symptoms, it is time to order a C113928 repair kit:
- Audible air leak from the vent port when valve should be closed
- Valve fails to pulse (no air blast)
- Weak pulse pressure (reduced cleaning effectiveness)
- Valve stays open continuously
- Visible cracking or hardening of the rubber when inspected
Conclusion
The ASCO SCXE353A061 pulse jet valve is a 3-inch submerged design for large dust collection systems. Key points:
- Model breakdown: SCXE = submerged, 353 = series, 061 = 3-inch
- Repair kit: C113928 (primary) or R143297 (alternate)
- Materials: NBR standard, FKM for high-temperature applications
- Sourcing: Genuine OEM and quality alternatives both available
- BM Pneumatics: Stocking both options with technical support
