Dump Valve (Diverter Valve)
The Dump Valve is a safety feature that is located
on the Ultra-High Pressure pump manifold and
controlled by the DUMP VALVE switch in the cap
switch panel. When activated, it diverts (dumps)
high pressure water from the blasting head to the
clean water tank immediately eliminating the high
pressure water at the blasting head. The Dump
Valve assembly consists of a hydraulic cylinder,
Shutoff Cartridge, diffuser tube and digital high
pressure sensor.
The Shutoff Cartridge is located inside the body of
the diverter valve assembly. It is generally open
and controlled by the DUMP VALVE 40K switch in
the panel in the cab of the truck. When the DUMP
VALVE switch is ON, the Shutoff Cartridge is closed
by the hydraulic cylinder forcing all high pressure
water to the blasting head. When the DUMP VALVE
switch is OFF, the hydraulic cylinder opens the
Shutoff Cartridge diverting (Dumping) high pres
-
sure water from the blasting head directly to the
bypass hose and the clean water tank. This allows
the Ultra-High Pressure pump to remain operat-
ing at maximum capacity, ready to provide high
pressure to the blasting head immediately. If the
charge water pump is turned off or fails, the UHP
pump must be shutdown immediately by press-
ing the EMERGENCY STOP button on the auxiliary
engine control panel in the cab.
When setting pressure ALWAYS ensure that the
system pressure drops to less than 100 PSI (7
Bar) immediately when the DUMP VALVE switch
is turned OFF. If system pressure does not im-
mediately drop below 100 PSI when the Dump
Valve is activated, do not use the equipment until
repairs are made to the Dump Valve.
Hydro-Throttle Controller
An electronic controller on the UHP pump manifold
senses manifold pressure to the blasting head and
automatically advances or decreases the auxiliary
engine speed when the DUMP VALVE switch is
turned ON or OFF. This feature is selected with
the THROTTLE MANUAL/AUTOMATIC mode toggle
switch in the auxiliary engine control panel. The
operator can choose to select MANUAL mode,
which allows the operator to set the maximum en-
gine RPM for the desired pressure, or AUTOMATIC
mode which automatically drops engine RPM to
idle when the DUMP VALVE switch is turned OFF
and advances engine RPM to the preset max op-
erating RPM when the DUMP VALVE switch is ON.

Hydro-Throttle Electronic Controller
The operator should consider the requirements
of the current operation and select the mode that
works best in that situation. The following is a brief
description of each mode.
