ASCO Red-Hat 8320G174 Solenoid Valve 1/4" NPT Brass 120V AC Explosion-Proof

The ASCO 8320G174 is a robust 3-way direct-acting solenoid valve designed for reliable control of air, inert gas, water, and light oil in industrial applications. Featuring a brass body with 1/4" NPT connections, this valve operates at 120V AC and handles pressures up to 100 PSI. Its explosion-proof enclosure (Types 3, 3S, 4, 4X, 6, 6P, 7, 9) makes it ideal for hazardous environments, such as chemical processing, oil and gas, and manufacturing facilities. Key benefits include fast response times, high durability, and low power consumption, with advantages over similar products like superior corrosion resistance and easy rebuildability using standard kits. Drawbacks may include higher initial cost compared to non-explosion-proof models and the need for proper electrical grounding. From image analysis, this unit appears to be in used but functional condition, with visible wear on wires and a rebuild kit reference, suggesting it may have been refurbished. No parent/child assets are evident. Estimated market price range: $150-$300 USD based on used condition and comparable eBay/automation supplier listings.
