Overview

Annovi Reverberi Mini Matic 4B unloader valve with a built-in bypass, rated to 180 bar (2,600 psi) and 18 litres per minute, with a 1/2" BSP female inlet and 3/8" BSP male outlet.

When the trigger gun is released, the valve relieves pump pressure and sends the water through the bypass, so the pump does not run against a closed outlet.
