12.0 Technical Information – [cont’d]
12.6 Motor and Valve Combination
IMPORTANT
The Skid-Pac is offered with multiple size motors.
Anytime the Skid-Pac is moved to a different carrier
or the motor or valve is replaced, always identify
which motor and valve package option is installed.
Poor performance or damage will result if the motor
and valve combination are improperly selected.
The Skid-Pac is standard equipped with a multi-
function control valve. Benefits of this valve include
optimized operation and improved reliability of critical
components such as the motor and bearings.
Refer to the Technical Data Table for motor and
valve options.
12.7 Control Valve – Adjustments, Function,
Identification & Port Connections
12.7.1 Control Valve – Adjustments
IMPORTANT
The valve is factory pre-set and requires no further
adjustments.
12.7.2 Control Valve – Function & Benefit
The four functions are:
1.
Flow regulator
– Protects the bearings from
damage by limiting the oil flow and preventing the
hydraulic motor from over-speeding.
2.
Pressure control
– Protects the hydraulic
components from over-pressure. This is factory
pre-set at the maximum operating pressure plus
200 psi (14 bar).
3.
Anti-cavitation circuit
- Controls deceleration of
the hydraulic motor and eccentric mass. Also
protects motor from damage on circuits not set
up with an unrestricted, free flowing, and open
return.
4.
Return line check valve
- Prevents reverse flow
to the hydraulic motor. Also provides a nominal
back-pressure to ensure the proper operation of
priority flow control valves, such as Allied’s AC40
and AC75.
12.7.3 Control Valve – Part Number Identification
& Port Connections
The part number of the control valve is stamped on
the manifold and just above the T2 port.
IMPORTANT
Attached to the mounting frame is the control valve.
In addition to the part number stamped on the valve
body, the connection ports are stamped P1, P2, T1
and T2. The supply hose is tagged with a red colored
cable tie marked ‘PRESSURE’.
