Bell & Gossett B146-11 Straight-Angle Flow Control Valve 1" Screwed/Flange
Flo-Control Valves are used for preventing gravity flow in forced water systems and to permit summer-winter operation of indirect water heaters. Flo-Control Valves in NPT sizes 3/4 - 2" are made in combination straight-angle patterns permitting installation in either horizontal or vertical pipe lines. Larger sizes may be furnished in either straight or angle patterns. Removeable top cap allows easy cleaning and service without removing pipe connections. Manual operating position for vertical lift disc to permit gravity circulation.
