FAQs

What is the primary advantage of the VSNC Series Solenoid Valve?

The primary advantage is its switchable 5/2 or 3/2 functionality, offering versatility for different actuator types and simplifying system design.

What does NAMUR certified mean for this valve?

NAMUR certification indicates that the valve meets specific industry standards for pneumatic control interfaces, ensuring compatibility with many automation systems and mounting hardware.

Can this valve be used in potentially explosive environments?

Yes, the valve is designed with an extended temperature range and is suitable for potentially explosive atmospheres, making it safe for hazardous environments.

What is the maximum recommended operating pressure?

The operating pressure range is 2.5 to 10 bar. While it can handle up to 10 bar, always ensure your system's design parameters are respected.

How do I switch between 5/2 and 3/2 function?

Switching is achieved by configuring the pilot air supply to the appropriate ports, as detailed in the product's technical documentation or the system's pneumatic diagram.

What is the nominal flow rate?

The standard nominal flow rate for this valve is 1250 liters per minute (l/min).

What material is the valve body made of?

The valve body is constructed from a robust aluminum alloy.

Troubleshooting

Valve does not actuate.

Check the pilot signal pressure and electrical connection (if applicable) to the solenoid. Ensure the operating pressure is within the 2.5-10 bar range. Verify the correct port is used for the pilot signal.

Leaking air.

Inspect all pneumatic connections for tightness. Check the valve seals for damage or wear. Ensure the valve is correctly switched to the desired port.

Slow or incomplete cylinder actuation.

Verify the nominal flow rate (1250 l/min) is sufficient for the actuator size. Check for restrictions in the pneumatic lines or exhaust ports. Ensure adequate supply pressure.

Incorrect switching between 5/2 and 3/2 modes.

Confirm the pilot signal is being directed to the correct port for the desired configuration. Review the system's pneumatic schematic.

Pros and Cons

Pros

  • Versatile 5/2 and 3/2 switching capability.
  • Durable aluminum alloy construction for industrial environments.
  • High nominal flow rate of 1250 l/min for efficient operation.
  • Suitable for potentially explosive atmospheres.
  • NAMUR certification ensures compatibility and adherence to standards.
  • Rotatable seal enhances installation flexibility.

Cons

  • Requires specific pneumatic knowledge for proper setup and maintenance.
  • G1/4 connection may require specific fittings for some existing systems.
  • Operating pressure range might be limiting for extremely high-pressure applications.
  • Primarily designed for pneumatic control, not electronic signal processing.

Setup, Compatibility & Care

Setup: Ensure the valve is installed in a clean environment, free from excessive dust or moisture. Connect pneumatic lines to the G1/4 ports, ensuring correct port identification for supply, exhaust, and actuator connections. The switchable functionality requires correct pilot signal routing for 5/2 or 3/2 operation, as per the system's requirements.

Compatibility: This valve is NAMUR certified, ensuring compatibility with standard NAMUR mounting interfaces and various EX solenoid systems. Verify that the required operating pressure (2.5-10 bar) and electrical specifications of the pilot signal (if applicable) match your control system.

Care: Regularly inspect the valve for signs of wear or damage. Keep external surfaces clean using a dry or slightly damp cloth; avoid harsh solvents. Ensure pneumatic lines are free from leaks. Periodic checks of pneumatic connections and the solenoid's actuation are recommended for optimal performance.
