In high-pressure or high-vibration piping systems, flange connections can often become a source of potential leaks. Our Butt welding ball valve is designed to provide a permanent, hermetic seal by welding directly into the pipeline, eliminating traditional joint failure points. Specifically, our Q61F-16C model features a compact, forged carbon steel body that is roughly 40% lighter than equivalent flanged valves, making it ideal for tight spaces or overhead installations where weight is a concern. This Butt welding ball valve is a trusted choice for high-pressure steam, thermal oil, and petrochemical gas lines.
We take great care in the manufacturing of each Butt welding ball valve, ensuring the welding ends are precision-machined to standard bevel specifications for easy field installation. To protect the internal PTFE or PEEK seals from heat damage during the welding process, we have optimized the valve body's heat dissipation structure. At Suhao Valve, we leverage our 30-year history to provide a valve that combines the reliability of a forged structure with the maintenance-free peace of mind that only a fully welded connection can offer.

Factory Customization & Strength
With our 16,600sqm production base, we maintain a large inventory of forged blanks to ensure rapid delivery of the Butt welding ball valve. We offer customization on pipe end extensions and specialized materials for cryogenic or high-temperature service. Our CNC gantry milling machines ensure that even the largest welded valves maintain perfect internal alignment for smooth operation.
Quality Control & After-Sales
Each Butt welding ball valve undergoes a 1.5x PN shell pressure test and 0.6MPa gas leak test. We provide a comprehensive MTR (Material Test Report) and a 12-month quality guarantee. Our after-sales team is available via video call to provide real-time guidance on field welding best practices to ensure your installation is successful.
FAQ
Q: How do I prevent the seals from burning during welding?
A: We provide detailed "cooldown" procedures and can supply valves with extended ends to move the heat away from the seat area.
Q: Is it available in stainless steel?
A: Yes, we offer F304 (Q61F-16P) and F316 versions for corrosive environments.
