The Circuit Setter calibrated balance valve is a
precision machined triple purpose balancing instrument. It is
precisely calibrated for use as a presettable balance valve, variable
orifice flow meter and positive shut-off service valve.
Valves are furnished with a calibrated nameplate and memory stop
indicator which permits the value to be preset to a fixed open position
and then closed for service without disturbing valve setting.
Valves are equipped with capped readout valves fitted with internal
check valves. Sizes 2-1/2″-4″ (brass ball) include a 1/4″ NPT tapped
and plugged drain port as standard.
