Fuel Solenoid Valves
Showing all 2 results
Fuel solenoid valves control the fuel flow in burners and liquid fuel lines on an electrical signal. The Unox YKT series comes normally closed (1/8″–1″) and normally open (3/8″–1″).

How Does It Work?
With the coil de-energised the valve is closed. When the coil is energised, the core is pulled up, the pilot orifice opens and the pressure difference lifts the diaphragm to let the medium flow. When power is removed, the valve closes.
With the coil de-energised the valve is open and the medium flows freely. When the coil is energised the valve closes; when power is removed it opens again.
Applications
- Oil burners
- Fuel supply lines
- Generator and boiler fuel lines
Selection and Installation
Install the solenoid valve with the coil on top and fit a strainer upstream. For high temperatures, specify the diaphragm and seal material when ordering. Specify the coil voltage (AC/DC) when ordering. Send us your working pressure, temperature and application, and our technical team will recommend the right model and size.
