Nominal sizes 30, 25 and 18

Main control valve for load sensing systems in monoblock design

Three directional control valves in a common housing form the base of the manifold valve plate in monoblock design. This results in the most compact package.

Design characteristics

  • basic block: three directional control valves of identical nominal size in one cast housing
  • designed for the Linde Synchron Control (LSC)-Load Sensing System
  • nominal sizes 30, 25 and 18
  • flows up to 600 l/min (size 30)
  • broad dimensioned diameters and flow-optimized design of the supply channels
  • extendable with directional control valves in sandwich design, in identical or differing nominal size
  • pressure cut-off and additional functions integrated in connection plate
  • special functions via intermediate plates
  • optionally with hydraulic or electric piloting

Sectional View

  • 1Load Sensing Directional Control Valve: shown as sub plate mounted valve, alternatively available as sandwich valve
  • 2Cross-sections: thoroughly dimensioned in several nominal sizes
  • 3Valve control spool: with integrated compensators and pressure copiers
  • 4Compensator: downstream, for compensation, one per side
  • 5Pressure copier: integrated in compensator, one per side
  • 6Centering spring: in two versions for two pilot pressure ranges
  • 7Shim: independently adjustable start of function on each side
  • 8Throttle check valve: in pilot pressure port, adjusting valve dynamics
  • 9Mechanical stroke limiter: independent flow limitation on each side
  • 10Pilot-operated pressure relief valves: with flat flow-pressure characteristic, make-up function optional
