Xylem-Bell & Gossett 117470 4" Flanged Circuit Setter Balance Valve CB-4F

The Xylem-Bell & Gossett 117470, also known as the CB-4F, is a versatile 4-inch flanged valve that functions as a triple threat in hydronic HVAC systems. It combines the functions of a positive shut-off valve, flow meter, and a balance valve into one.This multifunctional valve is essential to maximizing the effectiveness and performance of the system. It functions as a balancing valve, enabling accurate regulation and modification of the water flow through certain system circuits. By doing this, it is ensured that every area gets the appropriate amount of water, avoiding over- or under-supply in some places. This is made possible by the CB-4F's calibrated design, which converts handle position into a predetermined flow rate. It has built-in connections that allow a readout device to be connected, enabling personnel to measure and track the actual amount of flow that is going through the valve. For system validation and troubleshooting.
