Gymatic 3/B 21L+ Injector
Annovi Reverberi Gymatic 3B trapped pressure unloader valve with a built-in bypass and adjustable chemical injector, for Annovi Reverberi RK and HRK pumps. It is rated to 250 bar (3,625 psi) and 21 litres per minute, with a 1/2" BSP male inlet and 3/8" BSP male outlet.
When the trigger gun is released, the valve sends the water through the bypass and reduces the pressure at the pump to zero, while line pressure stays trapped in the hose until the gun is reopened. The injector is for low pressure detergent application and needs a suitable detergent nozzle or low pressure lance setting; flush it with clean water after use to prevent residue and blockages.
Fits Annovi Reverberi RK and HRK pumps.
