A pneumatic double-acting solenoid valve is a type of directional control valve used in pneumatic systems to control the actuation of double-acting pneumatic actuators, such as double-acting cylinders. These valves are operated electrically using a solenoid, allowing for remote and automated control of the compressed air flow
Key Features of Pneumatic Double Acting Solenoid Valves
1. Double-Acting Actuators
These valves are specifically designed to control double-acting pneumatic actuators, which have two air chambers and require compressed air for both extension and retraction
2. Solenoid Operation
The valve is equipped with a solenoid that, when energized, actuates the internal components to control the flow of compressed air
3. Valve Body
The body of the valve contains the necessary ports, chambers, and internal components such as spools or poppets that control the airflow
4. Inlet and Outlet Ports
Pneumatic double-acting solenoid valves have inlet and outlet ports for the flow of compressed air. The number and configuration of ports depend on the valve type
5. Position Indicator (Optional)
Some valves may include a position indicator to visually display the current state of the valve (open or closed)
Working Principle of Double Acting Solenoid Valve
Default Position
In the default or resting position, the valve is typically in a neutral state, blocking the flow of compressed air to both sides of the double-acting actuator
Solenoid Actuation
When the solenoid is energized, it actuates the internal components within the valve, allowing compressed air to flow to one side of the actuator
Actuator Extension
The compressed air pushes against one side of the actuator, causing it to extend
Solenoid Deactivation
When the solenoid is de-energized, the internal components return to the neutral position, blocking the flow of air to the extended side of the actuator
Actuator Retraction
Simultaneously, the valve opens the flow of compressed air to the opposite side of the actuator, allowing it to retract
Return to Default
When the actuation is complete, the valve returns to its default position, ready for the next cycle
