Study Notes
Solenoids
- A solenoid is an electromagnetic device that converts magnetism into mechanical movement.
- It is often used in conjunction with other mechanical parts to create a control element.
Solenoids in Oil and Gas Industry
- Commonly used in solenoid operated valves to control instrument air or lube oil flow.
Solenoid Valve Operation
- Electric coil positioned around the plunger creates a magnetic field when energized, pulling the plunger up and opening the orifice.
- The valve is closed when the solenoid is de-energized, and the plunger is pulled down by the spring.
Solenoid Valve Parts
- Coil/solenoid
- Spring
- Lead wires
- Plunger
- Inlet port
- Outlet port
- Valve body
- Orifice
Solenoid Valve Function
- Electromagnetic force from the coil holds the solenoid core down, allowing flow of instrument air to the valve actuator.
- When power to the coil is cut off, the solenoid core moves up, cutting off the instrument air supply to the actuator.
