Description
The ASCO 8266D69L is a direct-acting, 2-way normally closed solenoid valve engineered specifically for fuel oil shutoff applications. Featuring a robust brass body with stainless steel internal components, this valve delivers reliable, leak-tight shutoff across a wide range of fuel oil viscosities — from light distillates to heavy heated oils — making it a trusted solution for commercial and industrial burner systems.
When de-energized, the valve remains closed, providing a fail-safe shutoff that protects burner equipment and prevents unintended fuel flow. Upon energizing at 120VAC, the direct-acting solenoid opens the valve immediately, without requiring a minimum pressure differential to operate.
