Bell & Gossett, a Xylem brand, recently introduced a balancing valve that maintains the set flow rate within +/-5%, regardless of pressure fluctuation in the system. The Circuit Sentry Flo-Setter features a GPM dial that requires no adjustments once it is set, even if the system is changed.
The valve also maintains the set flow rate when installed next to a pipe bend or fitting. The valve’s integral P/T plugs allow verification of required differential pressure. The valve doesn’t require instruments, charts or wheels. It also doesn’t require minimum straight pipe lengths before or after the valve.
