Product Overview

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

The valve regulates the operating pressure and automatically diverts the water into bypass when the pressure washer trigger gun is released. This reduces the pressure inside the pump to zero, helping to protect the pump and associated components from operating against a closed outlet.

The line pressure remains trapped inside the high-pressure hose until the trigger gun is reopened. When the trigger is pulled, the unloader redirects the water through the outlet and allows the pressure washer to return to its normal operating pressure.

Rated for a maximum pressure of 250 Bar / 3,625 PSI and a maximum flow rate of 35 LPM, the Gymatic 3B features a 1/2″ male inlet, 3/8″ male outlet and built-in bypass.

Two versions are available. Order code 20080 fits Annovi Reverberi RK and XM pump ranges, while order code 20802fits the XW pump range.
