Load holding valve DLHV

  • Load holding valve DLHV-PC
  • Load holding valve DLHV-CC

Stable, vibration-free lowering manoeuvres

The DLHV load holding valve in combination with an Olsbergs Q200 or Q300 valve is characterized by vibration-free lowering manoeuvres, low operating pressure and pressure-compensation in both directions.
 

Valve DLHV solves infamous problem

Achieving safe, vibration-free lowering manoeuvres in a crane function in connection with load-sensing systems and conventional load holding valves is a well-known problem. 
Systems must often be set up such that an unnecessarily high operating pressure is built up on the piston rod side when lowering.

 

DLHV means low pressure on the piston rod side

Olsbergs load holding valves mean lowering manoeuvres are stable with very low operating pressures on the piston rod side.
