Solenoid Valves Used in Fuel Trains

A solenoid is a coil of electrical wires. When electricity passes through it, it becomes an electromagnet. A magnetic field is created through and around the coil. If a metallic core is placed within the coil, the electromagnetic field moves it.

The solenoid is used in several applications, including those involving solenoid valves. The flow of fluid through piping can be blocked by using a metallic plunger in the solenoid valve. When electricity is passed through the coil, the plunger moves and either blocks the orifice for the fluid flow or opens it. Solenoid valves are either of the “normally open” or “normally closed” variety. In the former, the orifice is closed when electricity is applied. The plunger moves to open the orifice when electricity is applied in “normally closed” solenoid valves.

Solenoid valves are either two-way or three-way. In two-way solenoid valves, there is one inlet and one outlet for fluid flow. In three-way valves, there is one inlet and two outlets piping for fluid to flow. When electricity is applied to the solenoid, the plunger moves and blocks one of the two orifices, allowing fluid to flow freely through it. When de-energized, the plunger moves back and blocks the first orifice allowing fluid to flow through the second orifice.

Profire Energy offers PF2100 and PF3100 BMS solutions. Solenoid valves are used in fuel trains that complement Burner Management System solutions. Profire Energy uses 12V or 24V, ASCO, Clark Cooper, and Peter Paul solenoid valves. To learn more about our products and solutions visit www.profireenergy.com.
