Product Overview

The Annovi Reverberi Gymatic 3B Unloader Valve is a pressure-regulating unloader valve and control set designed for Annovi Reverberi XW pressure washer pumps.

When the pressure washer trigger gun is released, the Gymatic 3B automatically diverts the water into bypass and reduces the pressure at the pump to zero. The line pressure remains trapped inside the high-pressure hose until the trigger gun is reopened.

This trapped-pressure operation helps protect the pump from working against a closed outlet while allowing the pressure washer to return to its normal operating pressure when the trigger is pulled.

The Gymatic 3B has a maximum pressure rating of 250 Bar / 3,625 PSI and supports water flow rates up to 35 LPM. It features a 1/2″ male inlet, 3/8″ male outlet and a built-in bypass.
