BILZ - Mechanical level control

In many industrial installations, it is crucial that machines remain horizontal and stable even under varying loads. The Bilz MPN series offers two high-class solutions - MPN-LCV and MPN-PVM - for mechanical-pneumatic height levelling of air suspension systems. These systems allow constant, automatic adjustment of the working level of the machine with millimetre or even hundredths of a millimetre precision.

Benefits & features

  • Stable machine level during operation: Continuous sensing with plunger keeps the machine horizontal despite load changes.
  • Automatic height adjustment: The air springs are automatically filled or vented depending on the plunger position.
  • Exact recovery: Whether you need 0.1 mm or 0.01 mm accuracy, there is a solution.
  • Complete systems: Both models are supplied as complete kits for up to 4 air springs - including valves, hoses and couplings.
  • Improved process quality and machine protection: Reduces the risk of misalignment, vibration and uneven loading on machines or tools.

MPN-LCV - Robust standard solution for FAEBI® and BiAir®

MPN-LCV is an extremely robust and galvanised system with proportional valve which regulates air flow based on load changes. It's designed for demanding industrial environments where reliability comes before precision.

Key characteristics:

  • Accuracy: ± 0,1 mm resetting accuracy
  • Air quality requirements: ISO 8573-1:2010 class 3.4.3
  • Pressure limitation: Max 6 bar
  • Compatibility:
    • FAEBI® and FAEBI®-HD rubber air springs
    • BiAir® membrane air springs
  • Variants:
    • MPN-LCV (Art.nr 61-0103)
    • MPN-LCV for BiAir® (Art.No 61-0012)
    • MPN-LCV-short-Pad-A (Art. No. 61-0054) - short version with insulating plunger pad for sensitive equipment
  • Field of application: Industrial level control for normal to moderate precision and interference suppression requirements.

🔸 MPN-PVM - High-precision solution for sensitive installations

MPN-PVM is a more advanced option where the highest possible accuracy is sought - for example in measuring machines, laboratory equipment or high-precision production. It has improved valve design and can meet much stricter air requirements.

Key characteristics:

  • Accuracy: ± 0.01 mm - for extreme precision
  • Air quality requirements: ISO 8573-1:2010
    • Class 2.4.2
    • Class 2.3.2 (if below 15 °C)
  • Pressure limitation: Max 6 bar
  • Compatibility:
    • BiAir® membrane air springs only
  • Variants:
    • MPN-PVM (Art.nr 61-0010)
    • MPN-PVM-short-Pad-A (Art.No. 61-0058) - with insulating plunger pad
  • Field of application: Applications with high demands on stability, vibration damping and process quality - for example in metrology, electronics and optics.
