Dwyer Instruments DBV-02 | Brass ball valve | 600 psi | Full port | 1/2"
The Dwyer DBV-02 brass ball valve is an economical 1/2" female-NPT hand-lever ball valve designed for commercial and industrial manual shutoff applications. Its full-port design helps minimize flow restriction when fully open, while the low-lead brass construction and PTFE sealing components provide a practical solution for threaded water and process piping systems.
Part Number: DBV-02
The Dwyer DBV-02 is a hand-operated brass ball valve with 1/2" female NPT connections on both ends, designed for straightforward manual isolation in commercial and industrial piping systems.
The valve features a brass body, cap, and stem, combined with PTFE seats and stem packing for a durable, low-friction sealing arrangement. Its blowout-proof stem is designed to remain captive under overpressure, providing an added safety feature during operation.
The full-port bore matches the internal diameter of the pipe, helping maintain flow with minimal restriction when the valve is fully open. Rated to 600 psi, the DBV-02 is suitable for general water and process shutoff points where threaded connections are the standard.
The low-lead brass construction and simple hand-lever operation make the DBV-02 a practical manual shutoff solution for 1/2" threaded piping.
If you need a different pipe size, the Dwyer range also includes the DBV-01, a 3/8" NPT brass ball valve with the same 600 psi pressure rating.
