Description
The ASCO SV311A02N6BF5 is a 1/4 inch, 2 way normally closed solenoid gas shut off valve used in commercial and industrial combustion and fuel gas control systems. It operates on 120 V AC and is designed to provide reliable on/off control of gas flow for pilot and main burner fuel lines. The valve uses a direct lift design with soft seating that ensures tight shut off and includes a 1/8 inch NPT downstream pipe test port with plug for routine pressure checks and maintenance. It has a flow coefficient (Cv) of about 1.1 and a nominal capacity around 59,000 BTU/hr. The valve’s aluminum body and NBR seals offer durability for commercial applications, and it’s suitable for ambient temperatures up to approximately 175°F. Typical maximum differential pressure rating is up to 15 psi, making it appropriate for low pressure gas control in HVAC and industrial burner systems.
