Extended Product Information

FAQs

What is the regulation range of this pressure regulator?

The Festo LR-1/4-D-MINI offers a regulation range from 0.5 to 12 bar.

What type of pneumatic connection does it use?

It uses a G1/4 pneumatic connection, which is also commonly referred to as a 1/4 inch connection.

What is the maximum input pressure the regulator can handle?

The maximum input pressure is 16 bar.

Can I use this regulator in a cold environment?

Yes, it can operate in temperatures as low as -10°C and up to +60°C.

What does 'pressure hysteresis' mean in this context?

Pressure hysteresis refers to the difference in pressure required to cause a specific change in output. This regulator has a maximum hysteresis of 0.2 bar, indicating a small variation in pressure control.

Does the regulator come with pressure gauges?

No, the regulator features dual pressure gauge connections, but the gauges themselves are not included and must be purchased separately if needed.

How do I prevent unauthorized changes to the pressure setting?

The regulator features a lockable control knob. Once the desired pressure is set, pull up the knob to lock it in place.

Troubleshooting

Pressure fluctuates or is unstable

Check for leaks in the pneumatic lines or connections. Ensure the hysteresis setting is appropriate for the application. Verify the input pressure is within the specified range (max 16 bar).

Regulator does not adjust pressure

Ensure the control knob is not locked. Verify that air is flowing through the regulator. Check for blockages in the air inlet or outlet ports.

Low flow rate despite correct pressure setting

Check for restrictions or blockages in the downstream pneumatic lines or the connected device. Ensure the connected device's requirements do not exceed the regulator's nominal flow rate (1500 l/min) or maximum capacity (12500 l/min).

Difficulty locking the control knob

Ensure the desired pressure has been set before attempting to lock. Check that the knob moves freely and is not obstructed.

Pros and Cons

Pros

  • Offers precise and stable air pressure control.
  • High nominal and maximum flow rates ensure efficiency.
  • Robust build quality suitable for industrial use.
  • Lockable feature enhances operational security.
  • Flexible mounting and monitoring options with dual gauge ports.

Cons

  • Requires specific G1/4 pneumatic fittings.
  • May require technical knowledge for optimal setup and calibration.
  • Hysteresis, while low, might be a consideration for extremely sensitive applications.
  • Dual gauge ports require separate gauge purchases if not already available.

Setup, Compatibility & Care

Setup:

  1. Ensure the air supply is depressurized before installation.
  2. Connect the inlet air supply to the port marked 'IN' using appropriate G1/4 fittings.
  3. Connect the downstream pneumatic device to the port marked 'OUT' using G1/4 fittings.
  4. If using pressure gauges, connect them to the available gauge ports.
  5. Slowly introduce compressed air and adjust the pressure using the control knob.
  6. Engage the lock by pulling up the knob once the desired pressure is set.

Compatibility:

  • Pneumatic Connection: G1/4 (also referred to as 1/4 inch connection).
  • Maximum Input Pressure: 16 bar.
  • Operating Temperature: -10°C to +60°C.
  • Designed for use with standard compressed air systems.

Care:

  • Regularly check for leaks in the connections.
  • Clean the exterior with a dry or slightly damp cloth. Avoid using solvents.
  • Periodically inspect the control knob and locking mechanism for smooth operation.
  • Ensure air intake is clean and free of debris to prevent internal component damage.
