The ElectricFastControl (EFC) is a modular system with a positive drive motor valve for each section and a single pressure dump valve, when all sections are switched to OFF.
The section valves incorporate a pressure dump. When the section is switched to OFF, the pressure in the line to the nozzles is relieved.
This results in instant shut-off at the nozzles. The EFC does not need any form of adjustment, e.g. pressure equalization.
