Product Description
This BW ball valve — BW meaning butt weld ends — is a two-piece stainless steel valve, model V-2B-BW, built for pipelines where a permanent, leak-tight joint matters more than easy removal. The body welds straight into the line, so there are no threads or gaskets at the connection to loosen or seep over time. Worried about drips? See our guide on why ball valves leak and how to prevent it.
Butt weld ends are welded end-to-end onto the pipe, giving a connection as strong as the pipe itself and a smooth bore with no internal pockets. It is a reduced port valve: the bore is smaller than the pipe bore, which keeps the body compact. If the line needs a full-bore welded valve, see the 3-piece extended butt weld valve below. The PTFE seat handles general-purpose media, and the lever handle shows open or closed at a glance.
304 and 316 stainless steel are both in stock. Choose 316 when the line carries chloride-bearing media — the molybdenum resists chloride pitting; 304 covers general service.

FAQ
What does BW mean on a ball valve? BW stands for butt weld. The valve ends are plain pipe ends that are welded end-to-end to the pipeline, rather than threaded (PT / NPT) or socket weld ends. Once welded in, there is no joint at the connection to loosen or seep.
What sizes are available? Four sizes: 1″, 1-1/2″, 2-1/2″ and 3″ — in 304 or 316 stainless steel, both in stock.
304 or 316 — which should I choose? Pick 316 for chloride-bearing media — the molybdenum resists chloride pitting. 304 is fine for general service. Both are stocked, so lead time is the same.
Why butt weld instead of threaded ends? A welded joint is permanent and leak-tight, with no threads or gaskets to loosen — a better fit for long runs and lines you do not plan to open. If you need to remove the valve for service, look at our two-piece threaded ball valve instead.
Will the weld ends match my pipe? Tell us your pipe standard and schedule when you request a quote, and we confirm the end preparation fits before anything ships.
How is this different from the 3-piece butt weld valve? The 3-piece extended butt weld valve opens in the line, so seats can be replaced without cutting the pipe, and its extended ends keep welding heat away from the seats. This two-piece version is reduced port and is the simpler choice for lines you weld once and leave alone.
Is it full port? No. The V-2B-BW is a reduced port valve — the bore is smaller than the pipe bore. If you need a full-bore valve on a welded line, choose the 3-piece extended butt weld ball valve.
