ASCO K3A542T Gas Solenoid Valve

The ASCO K3A542T is a 1/2-inch NPT gas shutoff solenoid valve designed to provide positive shutoff of pilot or main gas lines in commercial and industrial burners. This two‑way, normally closed valve operates from a 120 VAC coil (60 Hz) and has a Cv of 9 with a gas capacity up to 520,000 BTU/hour, making it suitable for medium to large gas-fired appliances. The inlet/outlet ports are 1/2" NPT, and the unit is rated for gas pressures up to about 6 psi depending on installation and gas type. For installation, ASCO specifies that the solenoid valve must be mounted upright or horizontal, and the K3A family is designed for safe shutoff in gas burners; the K3A542T‑120/60 variant confirms 120 VAC, 60 Hz operation. This model belongs to the ASCO Series K3A gas shutoff valves, a trusted choice in commercial gas controls.
