Based on Function:
1. Normally Closed (NC) Solenoid Valve: In this type of valve, the valve is closed when there is no power supply to the solenoid coil. The valve opens when the coil is energized.
2. Normally Open (NO) Solenoid Valve: In this type of valve, the valve is open when there is no power supply to the solenoid coil. The valve closes when the coil is energized.
3. Direct Acting Solenoid Valve: In this type of valve, the solenoid coil directly controls the valve stem, which opens or closes the valve.
4. Pilot Operated Solenoid Valve: In this type of valve, the solenoid coil controls a pilot valve, which in turn controls the main valve.
Based on Construction:
1. Brass Solenoid Valve: These valves are made of brass and are used in applications where the fluid or gas is not corrosive.
2. Stainless Steel Solenoid Valve: These valves are made of stainless steel and are used in applications where the fluid or gas is corrosive.
3. Plastic Solenoid Valve: These valves are made of plastic and are used in applications where the fluid or gas is not corrosive and the valve is not subjected to high pressure.
Based on Application:
1. Solenoid Water Valve: These valves are used in applications where water is the fluid being controlled.
2. Solenoid Air Valve: These valves are used in applications where gas is the fluid being controlled.
3. Steam Solenoid Valve: These valves are used in applications where steam is the fluid being controlled.
4. Fuel Solenoid Valve: These valves are used in applications where fuel is the fluid being controlled.
