MECHANICAL LEVEL
CONTROL SYSTEMS

Efficient level control systems for air spring isolators combined with the highest leveling constancy.

Mechanical-pneumatic level control systems from Bilz are an essential component for the optimum functioning of a vibration isolation system using the FAEBI® and FAEBI®-HD rubber air springs or BiAir® membrane air springs.

They prevent impermissible deflection of the isolators or inclination of the machine caused by load changes on a machine or an air spring-mounted machine or system.

NOTES

  • Supplied as a complete set which includes the 3 control valves and all necessary hose lines and connectors for 4 air springs. All components are also available individually as spare parts.
  • On the LCV variant the air flow can be reduced using the throttle valve should the control system tend to overshoot. The PVM variant can also be fitted with a throttle valve as an option.
  • In addition to the standard solutions listed here we also hold special versions with regard to material, flow, accuracy and restoring force.

FUNCTION OF THE VALVES

The level is continuously sensed by means of a plunger. The position of the plunger is directly applied to the slide valve. The air spring supplied with compressed air via the valve is pressurized or vented according to the position of the valve slide. The target level is adjusted by turning the knurled adjustment ring. The height and level of the machine is adjusted using three valves.

FUNCTION OF THE MECHANICAL-PNEUMATIC LEVEL CONTROL SYSTEMS

The valves are used to adjust and automatically regulate the air pressure inside the isolators according to the respective load by means of rapid ventilation and venting. This enables the highest degree of stability and effective isolation even with changes in the centre of gravity.

DESIGN

A level control system consists of at least three mechanicalpneumatic valves and three air springs (Fig. 1). If more isolators are required due to reasons of design or load, the system must still be operated in three controlled groups (Fig. 2), as otherwise it is statically overdetermined. This is achieved by using multiple isolators in parallel as a group (Fig. 2). Optionally, an additionally available maintenance unit for compressed air preparation can be connected upstream of the control valves.
