Butt Weld Valves
BW End Gate, Globe & Check Valves | Carbon Steel, Alloy Steel (WC6, WC9, C5), Stainless Steel | Class 150 to 2500 | ANSI B16.25
Butt Weld End Valves – The Strongest Connection for Critical Service
Supreme Valves India manufactures and exports premium butt weld (BW) end valves for high-pressure, high-temperature, and critical piping systems. Our butt weld valves feature end connections prepared to ANSI B16.25 with precision beveling for full-penetration welding directly to the pipeline – creating a permanent, leak-proof metallic bond that is stronger than the pipe itself.
Available in gate, globe, and check valve configurations, our butt weld valves are manufactured in carbon steel (WCB/A105), alloy steel (WC6, WC9, C5, C12), stainless steel (SS304, SS316, SS316L), and duplex/super duplex steel. Pressure classes range from Class 150 to 2500, with sizes from 1/2" to 24".
Why Choose Butt Weld End Valves?
Strongest Connection
Full-penetration weld joint is as strong as the pipe itself. No weak points in the piping system.
Zero Leakage
No gaskets, no bolts – the permanent metallic bond eliminates all potential leak paths.
Reduced Weight & Cost
No heavy flanges needed. Lower total installed cost compared to flanged equivalents.
High Pressure & Temperature
Standard for Class 1500 and 2500. Alloy steel (WC6) rated to 593°C continuous service.
Compact Footprint
No flange protrusion – saves space in congested piping layouts and skid-mounted systems.
Full Certification
MTC, hydro test certificates, radiography reports. Third-party inspection available (TPI, BVIS, Lloyds).

FAQ: Butt Weld Valves
What is the standard bevel angle for butt weld valve ends?
The standard bevel angle is 37.5° ± 2.5° as per ANSI B16.25, with a root face of 1.6 ± 0.8 mm. This preparation ensures full-penetration welding when the valve is installed in the pipeline.
When should I use butt weld ends vs flanged ends?
Butt weld ends are preferred for: permanent installations, high-pressure service (Class 600+), high-temperature service, space-constrained layouts, and anywhere zero-leakage is critical. Flanged ends are preferred when the valve needs to be removable for maintenance or replacement.
What is Sch.XXS (Extra Extra Strong)?
Sch.XXS refers to Extra Extra Strong wall thickness for pipe and valve ends. It provides the maximum wall thickness available for a given pipe size and is standard for Class 2500 butt weld valves. The thicker wall handles the extreme pressures and allows for full-penetration welding.
Can Supreme Valves supply butt weld valves for EPC projects?
Yes. Supreme Valves India regularly supplies butt weld valves to EPC contractors for power plant, refinery, and petrochemical projects. We provide complete documentation including MTC, test certificates, radiography reports, and coordinate third-party inspection as required.
