1 Piece Flanged Ball Valve

1 Piece Flanged Ball Valve Manufacturer in Africa

Product Introduction

African Valve is a prominent 1 Piece Flanged Ball Valve Manufacturer in Africa, manufacturing and supplying valves designed for positive shut-off and flow isolation in industrial piping systems. The one-piece body construction combined with flanged end connections provides a compact valve assembly that can be integrated into standard pipeline flanges while minimizing potential external leakage points. Available in multiple material grades, pressure classes, and operating configurations, 1 Piece Flanged Ball Valves are supplied to industrial projects across Nigeria, Egypt, South Africa, Kenya, Ghana, and other African markets, as well as international export destinations.

Why Choose a 1 Piece Flanged Ball Valve?

The 1 Piece Flanged Ball Valve is employed where there is a need for a small quarter turn isolation valve with flanged joints for pipelines. This valve works with a rotating ball, which may have either a full or reduced bore and which is aligned with the pipeline when open while blocking the flow when turned 90 degrees. As compared to the threaded type, the flanged joints give a tight joint through bolting and are therefore suitable for high pressure and larger pipes.

Materials & Construction

The valve is manufactured using:

• Carbon Steel – ASTM A216 WCB

• Stainless Steel – ASTM A351 CF8 / CF8M

• Duplex Stainless Steel – ASTM A995 Grade 4A

• Super Duplex Stainless Steel – ASTM A995 Grade 5A / Grade 6A

• Alloy Steel – ASTM A217 WC6 / WC9

• Ductile Iron – ASTM A536 Grade 65-45-12

Construction features include:

• One-piece cast or forged body construction

• Precision-machined stainless steel ball and stem
