Extended Product Information

FAQs

What is the primary advantage of the MHJ10-S-2,5-QS-6-HF valve?

The primary advantage is its ultra-fast switching time (as low as 1 ms) and excellent repeat accuracy (0.1 ms), making it ideal for high-speed automation and sorting tasks.

What is the maximum operating pressure for this valve?

The valve operates within a pressure range of 0.5 to 6 bar.

What does 'monostable 2/2 closed' mean?

It means the valve has two ports (2), two stable states (open/closed), and is normally closed (no flow) until energized by an electrical signal. It returns to its closed state when the signal is removed.

How is the pneumatic connection made?

The valve features a QS-6 quick-connect fitting for easy and secure pneumatic line connection.

What is the expected lifespan of this valve?

The MHJ series valves are designed for an extremely long service life, exceeding 5 billion switching cycles.

Can this valve be used for water control?

Yes, it can be used for fluid control, including water, provided the materials are compatible and the fluid is clean. Always verify material compatibility for specific fluids and conditions.

What is the maximum switching frequency?

The valve can achieve switching frequencies up to 1000 Hz.

Troubleshooting

Valve does not actuate (no flow change)

Check electrical connection and control signal voltage. Ensure the valve is receiving the correct signal and power. Verify system pressure is within the operating range (0.5-6 bar).

Slow or inconsistent switching

Inspect pneumatic lines for kinks or blockages. Ensure the QS-6 connection is secure and leak-free. Check for debris within the valve's air path if accessible or consider replacement.

Valve leaks air when de-energized

This is expected behavior for a monostable, normally closed valve when energized. If it leaks when de-energized, there may be internal wear or damage; consider servicing or replacing the valve.

Low flow rate

Confirm that the upstream air supply is adequate. Check for any restrictions or partially closed valves in the pneumatic line. Ensure the valve's nominal flow rate is sufficient for the application.

Pros and Cons

Pros

  • Extremely fast response times for dynamic processes.
  • High degree of precision and repeatability.
  • Durable design with a very long operational lifespan.
  • Compact and easy to integrate with QS-6 connections.
  • Suitable for high-flow industrial applications.

Cons

  • Requires a compatible control signal for operation.
  • Monostable design means it requires continuous power to stay open.
  • Specific flow rate and pressure ranges may limit some applications.
  • Not designed for manual override operations without a control signal.

Setup, Compatibility & Care

Setup:

  1. Ensure the pneumatic system pressure is within the 0.5 to 6 bar range.
  2. Connect the pneumatic line to the QS-6 port securely.
  3. Connect the electrical control signal to the valve's terminals, ensuring correct polarity if applicable.
  4. Verify that the valve is energized correctly to achieve the desired state (open when energized for this monostable, normally closed design).

Compatibility:

  • Pneumatic: Compatible with standard pneumatic systems using appropriate tubing for the QS-6 connection.
  • Electrical: Requires a control voltage compatible with the valve's electrical specification (refer to specific model datasheet for voltage range).
  • Fluid: Suitable for controlling air or other compatible industrial fluids. Check material compatibility for specific applications, especially with water.

Care:

  • Keep the valve and its connections clean and free from dust and debris.
  • Periodically inspect pneumatic lines for leaks.
  • Avoid operating the valve outside its specified pressure or temperature ranges.
  • No routine lubrication is typically required for this type of valve.
