Motors with 2-speed function must be ordered
with correct direction of rotation. With wrong
direction, load on the piston will be increased
3 times, which can give overheating of the
pistons. With the high pressure supply con-
nected to A-port, the motor shaft rotates in the
directions shown by arrows. R-motor rotates
clockwise, and L-motor counter-clockwise,
viewed from the motor shaft side. If the motor
is working in half displacement, and in not pre-
ferred "direction of rotation", allowed pressure
is maximum 210 bar (3000 psi).
Installation
Remove the protective cover from motor
mounting surface, place the O-rings (included
in delivery) in their proper position on the valve
mounting surface. Use grease to keep O-ring
fixed. Mount valve against the motor with the
ports in corresponding position.
4 pcs 1/2 UNC x 127 (5") included in delivery,
strength class 12.9 (ISO 898/1) Tightening
torque: 131 Nm (97 lbf·ft).
*For Marine applications, use Sikaflex or simi-
lar for corrosion protection.
Direction of rotation see also
page 40.
VTCA 600 will not automati-
cally shift from half to full
displacement at overload.
