ASCO 8043A 37 Solenoid Valve

The ASCO 8043A 37 Solenoid Valve is a Series 043 gas shut-off valve designed for reliable on/off control of fuel gas in commercial and industrial burners. It is a two‑way, normally closed device that uses a robust double‑disc design with over‑travel sealing to help ensure leak-tight operation across typical burner applications. The valve is available in CSA-certified configurations, with coil options shown in variants such as 8043A047CSA (120/60 VAC) and 8043A077CSA (120/60 VAC with 110/50 VAC variants), reflecting common electrical ratings for gas shut-off service. Construction materials and parts exposed to fluids include an aluminum body; seals and disc made of NBR; a washer of 302 stainless steel; the core tube of 304L stainless; the core and plugnut in 430F stainless; springs in 302F stainless; shading coil copper; and a zinc-plated steel pipe plug, all contributing to durability in harsh gas-fueled environments. Typical applications include controlling gas in commercial boilers, ovens, and other gas-fired equipment where a fail-safe shut-off is required.
