Product Overview
The ASCO SCG353A043 Pulse Valve is a high-performance, single-stage dust collector diaphragm valve engineered for reverse-pulse jet filter cleaning systems. Manufactured by Emerson under the ASCO Series 353 product line, this valve delivers short, high-energy sonic pressure pulses designed to dislodge accumulated dust cake from filter bags, sintered metal elements, and pleated filter cartridges. Its rapid opening and closing response maximizes cleaning shock wave efficiency while optimizing compressed air consumption across industrial dust collection baghouses.
Constructed with a rugged die-cast aluminium body and an integral solenoid pilot, the SCG353A043 features standard 3/4-inch G (ISO 228/1) threaded connections for clean in-line installation. It is equipped with a high-durability Hytrel thermoplastic elastomer diaphragm that ensures extended flex life and fast opening times across millions of operating cycles. The valve operates across an operating pressure range of 0.35 to 8.5 bar, providing dependable particulate removal in cement plants, metal smelting, mining, grain processing, and industrial environmental pollution control applications.

How do I find the right part for my system?
Three options. Search by part number if you have the OEM code from Parker, Danfoss, Linde, Kawasaki, Kayaba or Grundfos — our search recognises both manufacturer codes and aftermarket cross-references. Browse by category if you know the component type (pumps, valves, cylinders, etc.). Or send a spec sheet to our engineering desk and we'll cross-reference against our 3,000+ SKU catalogue within one business day.
Can you help me size a pump or valve for my application?
Yes — sizing support is included with every order. Send us your operating pressure, flow rate, viscosity, drive speed and duty cycle, and our engineers will recommend a suitable component from our catalogue with full datasheets. We don't custom-build parts ourselves, but we can spec the right OEM component for almost any standard industrial application.
Can you cross-reference a discontinued part?
Yes — cross-referencing is one of the things we do most. Send us the original part number (even if the manufacturer has dropped it) and our engineering desk will identify a current equivalent or compatible alternative. Cross-reference lookups are free and typically come back within 4 business hours.
