Product Configuration
The 40K Multi-Mode Valve can be configured in three different modes
depending on the equipment used and the needs of the user. Mode is
determined by the installation of a nozzle, a plug, or nothing in the mode
configuration port.
Figure 1 shows a cross section of the high-pressure valve assembly
used on the Multi-Mode Valve.
1) DUMP MODE:
For use with single gun systems. Reduces pressure to near atmospheric
pressure upon release of gun trigger. This mode is selected by remov-
ing the nozzle from the mode configuration port. Releasing gun trigger
will cause valve to shift water from blast gun to open atmospheric dump
port, making system act much like a standard dump style gun.
Operating in Dump Mode with frequent short cycles will
reduce the life of all components in the system, specifically hoses and
pressure gauges. All HP components will eventually fail due to fatigue
and frequent cycling from zero pressure to high pressure will shorten the
life of fluid end manifold and stuffing boxes. Consider running in constant
pressure mode instead.
