A failing 3-inch pulse valve cripples your baghouse cleaning cycle. The ASCO SCG353A060 pulse jet valve is a high-flow, 3-inch submerged pulse valve designed for large dust collection systems. This guide covers its specifications, key features, compatible repair kits, and buying recommendations.
You will learn the exact parameters of this valve, which industries rely on it, and how to source the correct repair kit when maintenance time comes. Whether you manage a cement plant, power station, or steel mill, this information will help you keep your dust collector running efficiently.
What Is the ASCO SCG353A060?
The SCG353A060 is a 3-inch, normally closed, internally piloted diaphragm valve from ASCO’s 353 series . It is specifically engineered for pulse jet baghouse dust collection systems.
Key identification points:
- Port Size: 3 inch (DN80)
- Valve Type: Submerged (also called “immersion” style)
- Body Material: Aluminum die-cast
- Connection: Threaded or push-to-fit depending on variant
The “submerged” design means the valve installs directly into the air manifold or header tank, with the diaphragm submerged in compressed air. This configuration maximizes flow and reduces pressure drop .
Technical Specifications
Understanding the operating parameters helps you verify compatibility with your system.
The valve’s internal pilot operation uses differential pressure rather than a mechanical spring, reducing moving parts and increasing reliability .
Key Features of the SCG353A060
High Flow Capacity for Large Systems
The 3-inch orifice delivers exceptional flow volume. For large baghouses with hundreds of filter bags, this valve provides the pulse energy needed to clean bags effectively in a single blast.
Submerged Design for Efficiency
Unlike angle-body valves that mount externally, the submerged SCG353A060 sits inside the air manifold. This eliminates external piping, reduces pressure losses, and allows for denser valve spacing on the header tank .
Durable Materials for Harsh Environments
The valve body is aluminum with stainless steel internal components. Seals and valve discs use NBR, while the diaphragm is neoprene – materials chosen for their resistance to oil mist, moisture, and temperature extremes .
Integrated Push-to-Connect Fittings
Some variants of the SCG353A060 accept push-in fittings, allowing fast installation without threaded pipe connections. This reduces labor time and eliminates potential leak points.

Compatible Repair Kits for SCG353A060
When your SCG353A060 needs maintenance, you need the correct repair kit. Based on manufacturer specifications, the C113928 diaphragm repair kit is the direct replacement for the 3-inch SCG353A060 and SCXE353A060 models .
C113928 Kit Contents
The genuine ASCO C113928 kit typically includes :
- Main diaphragm (NBR/Buna-N material)
- Pilot seal disc
- Internal springs
- Gaskets and o-rings
Material Options
| Material | Temperature Range | Best For |
|---|---|---|
| NBR (Buna-N) | -10°C to 70°C | Standard compressed air, oil resistance |
| FKM (Viton) | Up to 180°C | High-temperature applications |
For high-temperature environments (above 70°C), request the FKM/Viton version of the repair kit .
Alternative Kit Numbers
Depending on the exact valve variant, these alternative kit numbers may apply :
| Kit Part Number | Compatible Valve |
|---|---|
| C113928 | SCXE353A060 (3″) |
| R143297 | SCR353G060 (3″ variant) |
Always verify the valve model number on the nameplate before ordering a repair kit.
Applications and Industries
The ASCO SCG353A060 pulse jet valve is used in heavy industrial dust collection systems where large air volumes are required .
Cement and Aggregate Production
Cement plants use these 3-inch valves on baghouses serving kilns, clinker coolers, and crushers. The high pulse energy cleans filter bags heavily loaded with fine cement dust.
Power Generation
Coal-fired power plants rely on SCG353A060 valves for fly ash collection on boiler baghouses. The valves must withstand continuous operation and temperature fluctuations.
Steel and Metal Processing
Steel mills use these valves on dust collectors for electric arc furnaces, blast furnaces, and casting operations. The submerged design handles the high-pressure requirements of these applications.
Mining and Mineral Processing
Mine ventilation systems and mineral processing plants use SCG353A060 valves on large baghouses that handle high dust loads from crushing and screening operations .
Chemical and Pharmaceutical Manufacturing
Chemical plants use these valves where dust control is critical for product quality and worker safety. FKM repair kits are recommended for aggressive chemical environments.
OEM vs Aftermarket Repair Kits
When purchasing a repair kit for your SCG353A060, you have two options.
Genuine ASCO / Emerson Kits
Advantages:
- Guaranteed exact fit and material specifications
- OEM quality control
- Full warranty coverage
Disadvantages:
- Higher price (typically 2-3x aftermarket)
- Longer lead times from some distributors
Best for: Critical applications where failure is not acceptable, regulated industries, warranty requirements.
Aftermarket Compatible Kits
Advantages:
- 30-60% cost savings
- Often in stock for immediate shipping
- Multiple material options available
Disadvantages:
- Variable quality between suppliers
- Need to verify material claims
Best for: Routine maintenance, budget-conscious operations, non-critical applications.
Quality Checklist for Aftermarket Purchases
When evaluating an aftermarket supplier for C113928 kits, ask:
- Is the diaphragm material NBR, neoprene, or FKM?
- Does the kit include both the main diaphragm and pilot seal?
- Are material certifications available upon request?
- What is the warranty period? (Reputable suppliers offer 1.5 years)
Installation and Maintenance Tips
Proper installation maximizes the lifespan of your SCG353A060 and its repair kit.
Pre-Installation Checks
- Verify air quality: Install a 5-micron coalescing filter upstream. Moisture and oil degrade diaphragms over time.
- Inspect the valve body seat: Run a finger along the sealing surface. Nicks or pitting will cut the new diaphragm.
- Check the pilot port: Ensure the small orifice is clear of debris.
Installation Steps
- Depressurize the air tank completely
- Remove the coil and bonnet screws
- Extract the old diaphragm assembly
- Clean the valve body cavity thoroughly
- Install the new diaphragm without twisting
- Ensure the bleed hole is oriented correctly
- Replace the pilot seal and spring from the kit
- Tighten bonnet screws evenly in a crisscross pattern
Torque Specification
Use a torque wrench to avoid over-compression. For 3-inch ASCO pulse valves, the recommended bonnet torque is approximately 6–8 Nm (53–70 in-lbs).
Signs Your SCG353A060 Needs a Repair Kit
Recognize these failure symptoms early:
| Symptom | Likely Cause |
|---|---|
| Audible air leak from vent port | Torn or hardened diaphragm |
| Valve fails to pulse | Blocked pilot port or failed pilot seal |
| Valve stays open continuously | Damaged diaphragm or debris on seat |
| Weak pulse pressure | Worn diaphragm not sealing properly |
| Visible rubber cracking | Material fatigue or chemical attack |
If you observe any of these, order a C113928 repair kit and schedule replacement promptly.
