Bell & Gossett model SA-2" threaded, combination straight or angle-pattern flow-control valve. Its ductile iron body is rated to 125 psi and 250°F. Flo-Control valves prevent gravity flow in forced water systems and permit operation of indirect water heaters during both summer and winter. With a pressure drop of 1 to 6 feet of water this valve will perform from 1 to 46 GPM. See performance curves for your exact flow rate.
