AR Unloader | Annovi Reverberi Pump Bypass | Pressure Regulator
Annovi Reverberi manufactures AR Pumps for use in hot water and cold water pressure washers as well as offering a complete selection of bolt on unloaders. These pressure regulating valves bypass high pressure water from the pump head into the low pressure water inlet, protecting the pump from damage caused by over pressurization. We offer Gymatic 3/B unloader valves as well as the Mini-Matic 4/B unloaders with a variety of inlet thread designs, and selection of detergent soap injectors.
