How to Use L-Type Diverter Valve - 120VAC CR3-03: Examples, Pinouts, and Specs

The L-Type Diverter Valve - 120VAC CR3-03, manufactured by Generic, is an electromechanical device designed to control and redirect the flow of fluids in a system. This valve operates on a 120VAC power supply and is capable of switching fluid flow between two distinct paths. Its robust design and reliable operation make it suitable for a wide range of industrial and commercial applications.

• HVAC Systems: Used to control the flow of refrigerants or other fluids.
• Water Treatment Plants: Directs water flow between filtration or treatment stages.
• Industrial Automation: Redirects fluids in manufacturing processes.
• Irrigation Systems: Controls water flow between different zones.
• Food and Beverage Industry: Manages liquid flow in production lines.

The following table outlines the key technical details of the L-Type Diverter Valve - 120VAC CR3-03:

The L-Type Diverter Valve has a simple electrical connection interface. The table below describes the wiring:

1. Electrical Connection:

   • Connect the Live (L) and Neutral (N) terminals of the valve to a 120VAC power source.
   • Ensure the Ground (G) terminal is properly connected to the system ground to prevent electrical hazards.

2. Fluid Connection:

   • Attach the inlet port to the fluid source.
   • Connect the two outlet ports to the desired fluid paths.
   • Use appropriate fittings to ensure a leak-proof connection.

3. Operation:

   • When powered, the valve will switch the fluid flow between the two outlet paths.
   • The switching time is approximately 1-2 seconds.

• Voltage Compatibility: Ensure the power supply is 120VAC. Using a different voltage may damage the valve.
• Fluid Compatibility: Only use the valve with compatible fluids (e.g., water, oil, or non-corrosive liquids). Avoid using corrosive or highly viscous fluids.
• Pressure Limits: Do not exceed the maximum fluid pressure of 150 PSI to prevent damage.
• Mounting Orientation: Install the valve in a position that allows easy access for maintenance and ensures proper fluid flow.
• Safety Precautions: Always disconnect the power supply before performing any maintenance or installation work.

The L-Type Diverter Valve can be controlled using a relay module connected to an Arduino UNO. Below is an example code snippet:

// Example code to control the L-Type Diverter Valve using Arduino UNO
// The valve is connected to a relay module, which is controlled by pin 7.

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

void setup() {
  pinMode(relayPin, OUTPUT); // Set the relay pin as an output
  digitalWrite(relayPin, LOW); // Ensure the relay is off initially
}

void loop() {
  // Turn the valve ON (activate relay)
  digitalWrite(relayPin, HIGH);
  delay(5000); // Keep the valve ON for 5 seconds

  // Turn the valve OFF (deactivate relay)
  digitalWrite(relayPin, LOW);
  delay(5000); // Keep the valve OFF for 5 seconds
}

Note: Use a relay module rated for 120VAC to safely control the valve. Ensure proper isolation between the Arduino and the high-voltage circuit.

1. Can this valve handle corrosive fluids?

   • No, the valve is designed for water, oil, and other non-corrosive fluids. Using corrosive fluids may damage the internal components.

2. What happens if the power supply is interrupted?

   • The valve will remain in its last position until power is restored.

3. Can the valve be mounted in any orientation?

   • Yes, but it is recommended to mount it in a position that allows easy access for maintenance.

4. Is the valve suitable for outdoor use?

   • The valve is not weatherproof. Use it in a protected environment or install it in a weatherproof enclosure.
