G353A046 Remote Pilot Submerged Pulse Jet Valve

1. Basic Identification

• Model: G353A046 (AASF 353 Series Pulse Jet Valve)
• Serial No.: S346374
• Type: Remote air pilot submerged pulse jet valve (without built-in solenoid valve, actuated by external air supply)

Note: The model with built-in coil is SCG353A046; models starting with G stand for air pilot version, which requires an external small pilot solenoid valve for control.

2. Parameter Interpretation from Nameplate

• ORF. 52 mm: Orifice diameter 52 mm
• PIPE 1-1/2″: Connection size 1.5 inch (DN40)
• MEDIA AIR: Applicable medium: compressed air
• Operating pressure: 0.35 ~ 8.5 bar
• Valve body material: Die-cast aluminum alloy with anti-corrosion coating
• Standard seal: NBR nitrile rubber; FKM fluororubber optional for high-temperature working conditions

3. Structure & Working Principle

1. Structure Type: Submerged Pulse Jet Valve

    

   The valve is installed inside the air tank. The airflow discharges directly with much lower resistance than angle-type valves, delivering stronger jet force and higher flow capacity. It is a mainstream solution for bag dust collectors.

2. Actuation Mode: Remote Pilot Operation

    

   The quick-connect fitting on the top connects to the control air supply. A pulse controller drives an external small solenoid valve. Once pressure relief occurs, the diaphragm opens rapidly to release compressed air instantly for pulse cleaning of filter bags / filter cartridges.

4. Key Features

1. Ultra-fast opening & closing response, instant release of compressed air for high-efficiency dust cleaning.
2. Large flow passage design with 52 mm orifice, supporting simultaneous jet cleaning for multiple filter bags on large dust removal compartments.
3. Long-service-life diaphragm assembly with double-diaphragm structure, anti-fatigue for high-frequency pulse operation.
4. Main valve adopts spring-free structure for lower failure rate.
5. Quick-connect fitting on top; no PTFE tape required for convenient pilot air pipe installation.

5. Typical Application Scenarios

• Baghouse dust collectors, cartridge dust collectors and industrial dust extraction systems
• Cement plants, steel mills, metallurgy plants, asphalt mixing stations, waste incineration plants, powder processing industries
• Suitable for explosion-proof areas and high-temperature working conditions (FKM diaphragm for higher temperature resistance)

6. Sourcing & Replacement Key Points (for foreign trade & maintenance)

1. Avoid model confusion
   • G353A046: Air pilot version (this model, no coil)
   • SCG353A046: Solenoid operated version with built-in coil; they cannot be directly interchanged
2. Consumable spare part: diaphragm repair kit, critical stock item for after-sales service
3. Installation note: Must be matched with an external pilot solenoid valve. Recommended pilot air pressure: 0.4–0.6 MPa
4. Competitor alternative reference: Interchangeable with domestic 1.5″ air pilot submerged pulse valve (e.g. DMF-Y-40 air pilot type). Mounting dimensions are roughly compatible, while flow curves differ slightly.
