Dwyer Instruments SWBV-08 | Sweat connection brass ball valve | 400 psi | Full port | 2-1/2"
The Dwyer SWBV-08 is an economical 2-1/2" hand-lever brass ball valve with sweat (solder) connections, a full-port design, and a 400 psi pressure rating. It is designed for commercial and industrial copper piping applications requiring reliable manual shutoff.
Part Number: SWBV-08
The Dwyer SWBV-08 is a hand-lever brass ball valve designed for copper pipework, using sweat (solder) connections to join directly to compatible copper piping instead of threaded fittings.
The valve features a brass body, stem, and cap, with PTFE seats and stem packing that provide a durable, low-friction sealing arrangement. Its blowout-proof stem design helps keep the stem securely captive, including under overpressure conditions.
The full-port bore helps maintain low flow resistance when the valve is fully open. Compared with a reduced-port valve of the same size, this design helps minimize pressure drop across the valve during full-flow operation.
Rated to 400 psi at 2-1/2", the SWBV-08 is suitable for general manual shutoff duty on commercial and industrial water and process lines installed with copper piping.
For a different size and pressure requirement, the Dwyer SWBV-05 is also available as a sweat-connection brass ball valve with a 1-1/4" size and 600 psi pressure rating.
