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
