Load Sensing
MMV6
L90LS
M400LS

The directional control valve in the load sense system regulates the displacement of a variable displacement pump via a load signal line. The pump maintains a pressure difference between its outlet port and the highest load signal to supply pressure and flow to match the demand. These systems are the most advanced, offering optimum control characteristics with good efficiency/fuel economy.

Parker valves can be obtained with a large number of optional components and mountings such as:

 
  • A main pressure relief valve
  • Individually adjusted port-relief and anti-cavitation valves
  • Separate replenishing valves with counterpressure valves
  • Application adapted spools
  • A large selection of spool actuators
  • Subplate, stackable, or manifold styles
  • Single or multi-pump operation by stacked valves
  • Load holding checks
  • Crossover reliefs
  • Flow controls
  • Most valves available with on/off or proportional solenoids
  • Variable or fixed pumps (Options vary for different valves)
