Solenoid Valves
Types of Solenoid Valves
Solenoid valves provide electrically actuated control for hydraulic and pneumatic circuits. They are selected where automation systems require repeatable switching of flow paths or on/off control through an electrical signal.
- Solenoid valves used for automated on/off control of air or fluid flow.
- Valves selected to match required function and port standards.
- Solenoid valves chosen based on coil voltage and control requirements.
For manual valve options, compare Toggle Valves.
Key Selection Criteria for Solenoid Valves
- Valve function and flow path requirements for the circuit.
- Coil voltage and control method compatibility with the system.
- Pressure rating, temperature requirements, and media compatibility.
- Port size, thread standard, and sealing method compatibility.
- Duty cycle and environment, including contamination exposure.
Matching valve function and coil/control requirements helps ensure reliable automated control and reduces troubleshooting.
Frequently Asked Questions
What are solenoid valves used for in automation systems?
Solenoid valves are used to electrically control flow in pneumatic or hydraulic circuits, enabling automated switching and repeatable operation from a control signal.
What should I confirm for coil voltage and valve function?
Confirm coil voltage matches the control system, then verify valve function, port size, and pressure rating match the circuit requirements.
How do I choose solenoid valves for pneumatic vs hydraulic circuits?
Confirm the valve is rated for the media type and pressure range, and ensure seals/materials are compatible with compressed air or hydraulic fluid as required.
