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.

Model 3DV Triple Duty® Valves are manufactured with a brass body, chrome plated brass ball, and glass filled Noryl check valve with a stainless steel spring. They include two extended P/T valves and extended stem to allow for ease of installation in insulated systems, and include a choice of FNPT or rotatable flange inlet connection. They are available in sizes 1” through 2” and are suitable for up to 200 psi and 250°F. Model 3D (angle pattern) and 3DS (straight pattern) valves are manufactured with iron bodies, brass discs with EPDM seats, and stainless steel springs. They are available in sizes 2” – 16”, feature flanged and grooved end connections, and are suitable for either 175 psi (flanged) or 300 psi (grooved) pressure and 250°F.
