What is API 6D ball valve?

API 6D is the standard for pipeline ball valves, covering design, materials, face-to-face dimensions, pressure-temperature ratings, and testing requirements. API 6D ball valves are mandatory for many oil, gas, and petrochemical pipeline applications worldwide.

What types of ball valves do you manufacture?

We manufacture: Full Port and Reduced Port ball valves, 2-piece and 3-piece body designs, Flanged end (RF/RTJ), Threaded NPT/BSP, Socket Weld, Butt Weld, Trunnion Mounted for large sizes, Fire Safe API 607, and Double Block & Bleed (DBB) designs.

What materials are available for ball valves?

Carbon Steel WCB/A216, Stainless Steel SS304/SS316/SS316L, Duplex SS, Alloy 20, NAB C95800 for seawater, and 254 SMO. Seat materials: PTFE, RPTFE, Metal-to-Metal, and PEEK for high-temperature service.

Can ball valves be used for throttling?

Ball valves are primarily designed for on/off service. For throttling applications, we recommend V-notch ball valves or globe valves. Standard ball valves can be used for infrequent throttling but may experience seat wear at partially open positions.

What is the difference between trunnion mounted and floating ball valves?

Floating ball valves: The ball floats downstream and seats compress against the downstream seat to create the seal. Suitable for sizes up to 12 inch. Trunnion mounted: A bearing-supported ball that does not float. Required for sizes 14 inch and above, or for high-pressure applications above Class 600.

Do you supply fire-safe ball valves?

Yes. Our fire-safe ball valves comply with API 607 and ISO 10497 testing standards. They feature a secondary metal seat that engages during fire conditions, preventing leakage even if the primary PTFE seat is destroyed.

Ball Valve Types We Manufacture

Full Port Ball Valve

Unobstructed bore equals full pipeline flow. Ideal for slurries, viscous media, and where minimal pressure drop is critical.

1/4" to 4"

Reduced Port Ball Valve

Smaller ball and port than pipeline bore. Lower cost, lighter weight for standard on/off service.

1/2" to 12"

3-Piece Ball Valve

Bolted body design allows inline maintenance without removing the valve from pipeline. Preferred for critical service.

1/4" to 12"

Trunnion Mounted Ball Valve

Bearing-supported ball for high-pressure and large diameter applications. Lower operating torque, minimal seat wear.

4" to 24"

Fire Safe API 607

Secondary metal seat engages during fire. Tested to API 607 / ISO 10497. Essential for hydrocarbon service.

1" to 12"

NAB Seawater Ball Valve

C95800 Nickel Aluminium Bronze for seawater, offshore, and marine applications. Our specialty material.

2" to 12"

3-Way Ball Valve

L-port or T-port configurations for flow routing, diverting, or mixing applications. Threaded or flanged connections.

1/4" to 4"

V-Port Ball Valve

V-notch ball for throttling and flow regulation. Provides proportional flow characteristic. Used in dosing and blending.

1" to 8"
