Dwyer Instruments DBV-08 | Brass ball valve | 600 psi | Full port | 2-1/2"
The Dwyer DBV-08 brass ball valve is an economical 2-1/2" female-NPT hand-lever ball valve designed for commercial and industrial manual shutoff applications. Its full-port design provides minimal flow restriction when fully open, while the low-lead brass construction, PTFE seats and stem packing support reliable service in threaded piping systems.
Part Number: DBV-08
The Dwyer DBV-08 is a hand-operated brass ball valve featuring 2-1/2" female NPT connections on both ends. It is designed for straightforward manual isolation of commercial and industrial piping systems where threaded connections are required.
The valve uses brass for the body, cap, and stem, with PTFE seats and stem packing for a durable, low-friction sealing arrangement. Its blowout-proof stem remains captive under overpressure, providing an added safety feature during operation.
The full-port bore matches the internal diameter of the pipe, helping minimize flow restriction when the valve is fully open. With a maximum pressure rating of 600 psi, the DBV-08 is suitable for general water and process shutoff points where a robust threaded brass valve is required.
The DBV-08 uses low-lead brass construction and a simple hand-lever design, making it suitable for installations where reliable manual shutoff and easy operation are important.
If you need a different pipe size, the Dwyer range also includes the DBV-07, a 2" NPT brass ball valve with the same 600 psi pressure rating.
