Product Overview

The Annovi Reverberi VR 3B Unloader Valve is a pressure-regulating valve designed for compatible Annovi Reverberi pressure washer pumps.

When the pressure washer trigger gun is released, the VR 3B automatically relieves pressure from the pump and diverts the water through its built-in bypass. This helps prevent the pump from continuing to operate against a closed outlet and protects the pressure washer system during use.

The VR 3B has a maximum pressure rating of 300 Bar / 4,350 PSI and supports water flow rates up to 35 LPM. It features a 1/2″ female inlet, 3/8″ male outlet and an integrated bypass.

This unloader valve is compatible with Annovi Reverberi RW and RG pump ranges, making it suitable for pressure washer repairs, servicing and replacement installations.
