The PEV Backup Module is designed to bring the PEV electronic control valve to a user-defined position upon loss of power. The PBM can replace an upstream solenoid valve or user supplied uninterruptible power supply and offers a higher level of safety to the entire system. The PEV-PBM combination can be programmed to return to a full open, full closed, or defined position. The PBM features quick-disconnects so no user wiring is required; simply plug it into the PEV and all the necessary connections are complete.
