Flanged ball valves are quarter-turn shut-off valves with flanged ends, designed for secure and standardized connection in medium to high pressure piping systems.
Beyond Fluid is a professional stainless steel flanged ball valves manufacturer in China, supplying SS304 & SS316 flanged ball valves for industrial projects, wholesalers, distributors, and OEMs.
Flange Standard: ANSI / DIN /JIS | Pressure Class: Class 150 / 300 | Size Range: DN15 – DN300
A flanged ball valve is a quarter-turn shut-off valve equipped with flanged ends, allowing it to be bolted directly to pipeline flanges for a secure and standardized connection.
By rotating the handle 90 degrees, the valve opens or closes flow through a precision-machined ball. Flanged ball valves are commonly used in medium to high pressure systems where strength, sealing reliability, and alignment accuracy are critical.
Compared with threaded ball valves, flanged ball valves are better suited for larger pipe sizes and industrial applications such as oil & gas, chemical processing, power plants, and water treatment systems.
Feature:
A 1 PC flanged ball valve features a single solid body with flanged ends, controlling fluid flow by rotating the internal ball 90 degrees.
A 2 PC flanged ball valve features two connected body pieces with flanged ends, allowing easy installation into a piping system.
A 3 PC flanged ball valve allows easy maintenance by removing the central body without disrupting the pipeline, ensuring secure connections.
A 3-way flanged ball valve controls fluid flow in multiple directions, using a T-shaped or L-shaped bore to divert or mix.
A flanged gate valve controls fluid flow by raising or lowering a flat gate within the valve body.
A flanged globe valve controls fluid flow with a movable disk on a stationary ring seat in a spherical body.

How to choose: Select ANSI flanged ball valves for projects following ASME standards, commonly used in the USA and Middle East. Choose DIN flanged ball valves for European and metric-based piping systems. Always confirm flange standard, pressure rating, and bolt dimensions before ordering.
Selecting the right flanged ball valve depends on pressure class, valve structure, ball design, and material. The guidelines below help ensure safe operation and long-term reliability.
Class 150 flanged ball valves are suitable for low to medium pressure applications and are widely used in water systems, general industry, and standard process lines.
Class 300 flanged ball valves are designed for higher pressure and temperature conditions, commonly used in oil & gas, chemical processing, and critical industrial pipelines.
Recommendation: Choose Class 150 for standard pressure systems; select Class 300 for higher pressure or more demanding operating conditions.
1-piece flanged ball valves feature a compact, one-body design and are mainly used for simple applications where maintenance is not required.
2-piece flanged ball valves offer a balance between strength and cost, making them the most common choice for industrial on/off flow control.
3-piece flanged ball valves allow inline maintenance without removing the valve from the pipeline, ideal for systems requiring frequent inspection or cleaning.
Recommendation: Choose 2-piece for most applications; use 3-piece when maintenance access is important.
Floating ball valves rely on line pressure to seat the ball against the downstream seat. They are suitable for small to medium sizes and moderate pressure ratings.
Trunnion mounted ball valves support the ball with upper and lower trunnions, reducing operating torque and providing better stability for large sizes and high-pressure applications.
Recommendation: Choose floating ball for smaller sizes and lower pressure; select trunnion mounted designs for large diameter or high-pressure systems.
SS304 flanged ball valves provide good corrosion resistance for most general industrial applications, including water, air, and mild chemical environments.
SS316 flanged ball valves offer enhanced resistance to corrosion, especially in chloride-rich or aggressive media, making them suitable for chemical plants and Middle East outdoor installations.
Recommendation: Use SS316 for corrosive or harsh environments; select SS304 for standard service conditions.
