Description
The ASCO K3A682V is a commercial‑grade 1‑1/2 inch, 2‑way normally closed (N/C) gas solenoid shut‑off valve designed for high‑pressure fuel gas control in combustion systems. It operates on 120 V AC and is engineered to provide positive shut‑off on pilot or main gas lines for larger commercial and industrial burners, boilers, furnaces, and HVAC combustion equipment. The valve body is made from durable aluminum with steel and stainless internal components, and it includes upstream and downstream 1/8 inch NPT pressure test ports for routine system maintenance and safety verification. These valves are suitable for service at up to about 5 psi, with a high BTU capacity typically around 1.5 million BTU/hr.
Key Features
- 2‑way normally closed configuration — the valve remains closed when not energized and opens when powered, providing reliable safety shut‑off.
- 1‑1/2" NPT threaded inlet/outlet sizing for larger gas lines.
- Pilot‑operated design for stable control in high‑pressure gas applications.
- Rugged aluminum body with corrosion‑resistant internal trim and stainless steel parts.
- Built‑in upstream and downstream pressure tap ports (with plugs) facilitate annual testing and maintenance.
- Suitable for ambient temperatures up to about 175°F.
- Rated for approximately 5 psi differential, matching typical industrial burner gas pressures.
