ASCO JB8266D23L Direct Acting Fuel Oil Solenoid Shutoff Valve
The ASCO JB8266D23L is a heavy-duty, direct-acting, 2-way normally closed solenoid valve engineered specifically for fuel oil shutoff applications. With a robust brass body and stainless steel internal components, this valve delivers reliable, leak-tight shutoff across a broad range of fuel oil viscosities — from light distillates to heavy heated oils. It is ideal for commercial and industrial burner systems, fuel oil supply lines, and heating equipment requiring dependable automatic shutoff control.
Key Features
- Direct-acting operation — opens immediately upon energization, no minimum pressure differential required
- 2-way, normally closed (N/C) configuration for fail-safe fuel shutoff
- 3/8″ NPT pipe connection for easy installation into standard fuel oil piping
- 120VAC coil voltage for compatibility with standard commercial control circuits
- 1.2 Cv flow coefficient for efficient fuel oil flow management
- Brass body construction for corrosion resistance in fuel oil service
