Dwyer Instruments SWBV-09 | Sweat connection brass ball valve | 400 psi | Full port | 3"
The Dwyer SWBV-09 is an economical 3" hand-lever brass ball valve with sweat (solder) connections, a full-port design, and a 400 psi pressure rating. Designed for commercial and industrial copper piping, it provides reliable manual shutoff for water and process lines.
Part Number: SWBV-09
The Dwyer SWBV-09 is a hand-lever brass ball valve designed for copper pipework, using sweat (solder) connections for direct installation into compatible copper lines. This connection method provides a practical alternative to threaded fittings for commercial and industrial piping applications.
The valve features a brass body, stem, and cap, along with PTFE seats and stem packing for a durable, low-friction seal. Its blowout-proof stem design helps keep the stem securely captive, including under overpressure conditions.
A full-port bore helps maintain low flow resistance when the valve is fully open. Compared with a reduced-port valve of the same nominal size, the full-port design can help minimize pressure drop across the valve.
Rated to 400 psi at 3", the SWBV-09 is suitable for general manual shutoff duty on commercial and industrial water and process lines using copper piping.
For an adjacent size in the same valve range, the Dwyer SWBV-08 is available with a 2-1/2" size, sweat connection, full-port design, and 400 psi pressure rating.
