Xylem-Bell & Gossett 117632 3/4" NPT Circuit Sentry Flo-Setter II Balance Valve

The Bell & Gossett 117632 Circuit Sentry Flo-Setter II is a 3/4" NPT pressure-independent flow limiting valve designed for flow regulation in hydronic heating and cooling systems. This valve operates within a temperature range of 14°F to 250°F and features a flow capacity range of 0.45 to 8.5 GPM. The valve maintains the set flow rate within +/- 5% regardless of pressure fluctuations.

Key Features:

• GPM flow setting adjustment dial allows flow rate changes independently of differential pressure without system shutdown
• Internal flow setting/differential pressure regulating element provides integral isolation and shutoff capability
• Easy to install and maintains set flow rate even when installed next to a pipe bend or fitting, with easy-to-read gallons per minute scale on lockable handle
• External locking handle and two capped 1/4" pressure/temperature test ports
• Brass body construction ensures durability and reliability in demanding conditions
• No minimum straight pipe lengths required before or after the valve

Simply set the flow and the Circuit Sentry Flo-Setter valve does the rest—once set, no adjustments are required even if the pressure varies or the system is changed. The valve is rated for 375 psig maximum working pressure. This valve simplifies hydronic system balancing by automatically maintaining set flow rates, reducing commissioning time and improving system efficiency.
