Bell & Gossett 3D-3S Series 132133 Triple Duty Angle Valve, 3 in Nominal, Flanged, 800 gpm, 175 psi, 250 deg F

The Bell & Gossett Triple Duty valve is a combination valve that provides all of the functions normally required on the discharge side of hydronic pump systems. The design combines three valves into one: a calibrated balance valve, a spring loaded check valve, and an isolation/shut-off valve. The combination of multiple valves helps save space and reduces installation time and money. All Triple Duty Valves features a calibrated nameplate designed to allow you to accurately balance your system and throttle excess flow. Model 3DV valves utilize a calibrated ball valve design that also provides complete shut-off. The larger Model 3D and 3DS valves utilize a disc style globe valve design that also features a soft seat design that provides complete shut-off and prevents valve chatter. Additionally all valves feature a memory stop or memory button to allow you to return the valve to its set position after shut-off. All B&G Triple Duty Valves also include a spring loaded check valve to prevent backflow and gravity circulation.
