Connecting the shuttle valve
A shuttle valve should be installed in the load sense
line. See Figure 5 for proper mounting and orientation
of the shuttle valve. This way, when in rest, the ball
inside the shuttle valve floats inside the valve, which
will benefit the response for the load sense signal. In
addition, it is important that the shuttle valve is
installed as close to the pump as possible.
Tip!:
In case the wheels of the tractor steering, as
soon as the hydraulics of the tractor are
operated; a non-return valve should be mounted
in the load sense line from the manifold. The
non-return valve should let oil pass from the
manifold to the check valve/pump and should
block in opposite direction.
Tip!:
A shuttle valve for CNH tractors can be provided
by SBG (order no. SBG10713) or the local CNH
dealer (order no. 82018814).
