Block-system rotor that holds its arc, in full circle or adjustable part circle. B Series rotors deliver the gear drive, nozzle performance, and through-the-top servicing you expect from Hunter, in a block-system configuration that is easier on the budget. Ideal for new construction, retrofits, and system upgrades that call for block control.
This Configuration – Block Check Valve
Block check valve holds back up to 7 ft of elevation change.
Ships with the #25 nozzle installed. Nozzles are field-swappable with Hunter’s QuickChange™ system, so you can retune radius and flow without pulling the rotor.
