Pneumatic Load sensing valve

The automatic load sensing valve ( LSV )–pneumatically controlled, is installed in vehicles (motor vehicles, trailers and articulated trailers) with pneumatic braking systems and pneumatic suspensions. The braking pressure in the pneumatic braking system, and with that the braking force, is controlled to correspond to the static load condition of the particular vehicle. When the static load changes, the pressure in the suspension bellows changes continuously via the pneumatic suspension valve.

The effective pressure ratio iR = pe1 : pe2, which can be easily reconstructed in the workshop, is the practical reference point for adjustment.
