Steering System Components
Antijerk Valves
Description
Antijerk Valves provide smoother steering on articulated vehicles,
such as Wheel Loaders. This is achieved by a pressure
sequence valve mounted on a block. (For more information
see Vickers ® Screw-in Cartridge Valves Cat. V-VLOV-MC001-
E2.)
Features
Dramatically reduces jerk when steering is stopped quickly
and while making aggressive changes in direction. The valve
works by monitoring the margin pressure acting on the
steering valve. Margin spikes when steering wheel speed is
reduced aggressively. When this occurs a small amount of
damping flow is allowed across the turn ports. Unlike accumulators
this valve will not have a negative affect on roading
performance, and it is more cost effective than cushion
valves.
Applications
CF1 is supply from the pump or priority valve, CF2 should
connect to the steering valve UPSTREAM of any check
valves, LS1 & LS2 are the steering valve load-sense connection,
R&L are pass through ports for the turn lines. The
setting of the valve needs to be higher than the normal difference
in pressures between CF and LS, i.e. if CF-LS is 150PSI
then a good setting to start with is 200PSI.
