Multi-Mode Options
Illustrated
1) PRESSURIZED DUMP MODE
(Multi Gun Operation)
In this arrangement the Multi-
Mode Control Valve dumps the
unused flow from the pump,
when the gun is not being operated,
through a single orifice
nozzle installed in the inlet to the
Energy Diffuser Assembly. The
single orifice is chosen to have
the same flow rating as the combined
orifices on the gun or
lance. The jet from the single
orifice nozzle discharges into the
Energy Absorber Guide Tube and strikes the Jet Impact Slug,
which destroys most of the energy of the jet. The flow leaves
the Guide Tube through a series of holes and exits to
atmosphere through the Energy Absorber Cap and Street
Elbow.
2) LOW PRESSURE DUMP MODE
(Single Gun Operation)
This is for use with a plunger pump, when only one lance or
gun wil be used at any time. The single dump orifice and
Energy Diffuser Assembly are omitted so that whenever the
Multi-Mode Control Valve shifts to the dump mode, the
pressure in the entire system will fall to zero. Actuating
the trigger on the gun or lance closes the dump and restores
pressure throughout the system.
3) DRY SHUT-OFF MODE
This is primarily intended for use with an intensifier pump and
assumes that the pressurized system has a flow compensation
device, which will discharge or control theexcess flow when a
gun or lance is shut off. To operate the Multi-Mode Control
Valve in this mode, an orifice plug is substituted for the orifice
in the nozzle holder. Actuating the trigger on the gun signals
the Multi-Mode Control Valve to initiate the high-pressure flow
to the gun. Releasing the trigger allows the Multi-Mode Control
Valve to stop the flow, which MUST be compensated for
elsewhere in the system.
