6.5 CONTROL VALVE ACTUATOR
The control valve actuator has three positions, OPEN, OFF, and CLOSE. The control valve actuator includes a deadman safety feature
which returns the control valve actuator to the OFF position (neutral) when released. When the control valve is in the OFF position, the
tool movement stops, and holds position and load. The control valve actuator controls the motor and hydraulic pump. Electronics within
the tool prevent electrical overload during operation.
Verify operation of control valve actuator by checking to see it returns automatically to the neutral position when released.
