Description
Overview
The ASCO JB821437CSA is a 2-way, normally open solenoid valve engineered specifically for fuel gas vent applications in commercial and industrial HVAC and combustion systems. Designed to provide reliable, fast-acting shutoff and venting control, this valve delivers consistent performance in demanding gas-handling environments.
Key Features
- 2-way, normally open (N.O.) configuration — valve opens when de-energized for safe venting
- 3/4″ NPT pipe connection for straightforward installation into standard gas piping
- 120VAC operating voltage for compatibility with common commercial control circuits
- 11 Cv flow coefficient supporting up to 659,000 BTU/hr capacity
- Operating pressure range: 0–5 PSI, suitable for low-pressure fuel gas vent service
- Aluminum body construction — lightweight, corrosion-resistant, and durable
- NBR (Buna-N) seals for reliable compatibility with natural gas and other fuel gas media
- NEMA 1 enclosure with integrated junction box for clean, protected wiring connections

Application
The ASCO JB821437CSA is ideal for use as a fuel gas vent valve in commercial burner systems, boilers, and industrial combustion equipment. The normally open design ensures the vent path remains open during a de-energized (safe) state, making it well-suited for safety vent applications between redundant gas safety shutoff valves. The NEMA 1 junction box enclosure simplifies field wiring and protects electrical connections in indoor, non-hazardous locations.
