PV = Piloted Variable Capacity: Includes four air piloted supply valves and non-return valves for independent control of each station via separate remote pilot signals with a constant air supply to the pump base inlet port. With this option, one pump assembly can have up to 6 different capacities that can be selected to exactly suit the system requirements at any given time. A quick release valve (RP, RT) should also be specified. When RT is used, the Pilot line is connected at the time of installation to suit the application.
