How to Use 5/2 way 24v dc single selenoid valve: Examples, Pinouts, and Specs

The Aeroflex 5/2 Way 24V DC Single Solenoid Valve (Part ID: VALVE) is a versatile component used to control the flow of air or fluid in pneumatic or hydraulic systems. This valve features five ports and two positions, allowing for efficient and precise control of fluid dynamics. It operates on a 24V DC power supply and is commonly used in industrial automation, robotics, and various fluid control applications.

1. Power Supply Connection: Connect the solenoid positive pin (Pin 1) to a 24V DC power supply and the solenoid negative pin (Pin 2) to the ground (GND).
2. Port Connections:
   • Connect Port 1 (P) to the pressure source.
   • Connect Port 2 (A) to the first output line.
   • Connect Port 4 (B) to the second output line.
   • Connect Port 3 (R) and Port 5 (S) to the exhaust lines.
3. Control Signal: Use a microcontroller or a relay to control the solenoid valve. When the solenoid is energized, the valve switches positions, directing the flow from Port 1 to either Port 2 or Port 4.

• Voltage Rating: Ensure that the power supply voltage is strictly 24V DC to avoid damaging the solenoid.
• Pressure Range: Operate within the specified pressure range (0.15 to 0.8 MPa) to ensure optimal performance.
• Temperature Range: Use the valve within the operating temperature range (-10 to 50°C) to prevent malfunction.
• Regular Maintenance: Periodically check for any blockages or wear in the ports and clean them as necessary.

Below is an example code to control the Aeroflex 5/2 Way 24V DC Single Solenoid Valve using an Arduino UNO.

// Define the pin connected to the relay module
const int relayPin = 7;

void setup() {
  // Initialize the relay pin as an output
  pinMode(relayPin, OUTPUT);
  // Start with the relay off
  digitalWrite(relayPin, LOW);
}

void loop() {
  // Turn the relay on (energize the solenoid)
  digitalWrite(relayPin, HIGH);
  delay(1000); // Keep the solenoid energized for 1 second

  // Turn the relay off (de-energize the solenoid)
  digitalWrite(relayPin, LOW);
  delay(1000); // Keep the solenoid de-energized for 1 second
}

1. Valve Not Switching Positions:
   • Solution: Check the power supply voltage and ensure it is 24V DC. Verify the connections to the solenoid.
2. Slow Response Time:
   • Solution: Ensure the operating pressure is within the specified range. Check for any blockages in the ports.
3. Leakage from Exhaust Ports:
   • Solution: Inspect the exhaust ports for any debris or damage. Clean or replace the exhaust filters if necessary.

• Check Connections: Ensure all electrical and pneumatic connections are secure and correctly configured.
• Verify Power Supply: Use a multimeter to check the voltage at the solenoid terminals.
• Inspect for Blockages: Regularly inspect the ports and lines for any blockages or debris that could impede flow.
• Consult Manufacturer: If issues persist, refer to the Aeroflex technical support for further assistance.

By following this documentation, users can effectively utilize the Aeroflex 5/2 Way 24V DC Single Solenoid Valve in their applications, ensuring reliable and efficient fluid control.
