These valves are intented to replace the
traditional mechanical or hydraulic-compensating (i.e. slave cylinder) systems
used on front loaders to maintain the bucket in a fixed attitude during raising
and lowering.
The valves make use of flow dividers to synchronise the
lift and bucket cylinder movements such that the bucket remains in the same
attitude whilst moving up and down. The ratio of the flow division is
adjustable to suit the ratio between the lift and bucket cylinder size. This
system is applicable to open, closed and load-sensing circuits and is intended
(amongst others) for such applications as: - Tractor front loaders - Skid-steer
loaders - Small wheeled-loaders, etc.
This small, easily connected
valve offers highly repeatable levelling and low internal leakage.
