Solenoid Valves require an electrical signal to open or close the valve.
When the valve is ‘Normally Closed’, the valve requires electrical power to open.
When the valve is ‘Normally Open’, the valve requires power to close.

Due to the electrical actuation, Solenoid Valves fall into two categories:

Safe Area.
Explosive Area.

Body Materials:

Brass. Used for general purpose fluids
316 Stainless Steel. Used for corrosive fluids
304 Stainless Steel. Used for corrosive fluids
Aluminium. Lightweight material usually found in pneumatic applications
Plastic. Cheap body material, but can sometimes be specified for corrosive liquids
PTFE. Usually used for very corrosive liquids such as acids
