How does a purge valve work in an EVAP system?
EVAP Purge Valve Operation. A flap in the EVAP purge valve body restricts the motion of fluid and is magnetically attracted by the voltage applied via the valve’s electrical contacts. The flap is attracted to a coil in the evaporative purge system, which closes the valve and blocks the passage of fluids.
