DTC-BALL VALVE
DTC supplies high-quality industrial ball valves for reliable shut-off and flow control applications. Available in floating and trunnion mounted designs, carbon steel, stainless steel, and alloy steel materials, manufactured according to API 6D, API 598, and ASME B16.34 standards.
A ball valve is a quarter-turn valve that uses a rotating ball with a bore through its center to control fluid flow. When the valve is opened, the ball rotates 90 degrees to align the bore with the pipeline, allowing fluid to pass through. When closed, the solid side of the ball blocks the flow path to provide reliable shut-off.
Due to its simple structure, fast operation, low pressure loss, and excellent sealing performance, ball valves are widely used in industrial piping systems.
DTC supplies industrial ball valves in various designs, including floating ball valves and trunnion mounted ball valves, with options for flanged, threaded, and welded ends. Available materials include carbon steel, stainless steel, and alloy steel for different working conditions.
Ball valves require only a 90° rotation to fully open or close, allowing quick operation and emergency shut-off.
The precision-machined ball and seat design provides reliable sealing with minimal leakage.
The full-port design allows smooth fluid flow with reduced turbulence and energy loss.
Suitable for liquids, gases, steam, and many industrial media.
High-quality materials and robust construction ensure reliable operation under demanding conditions.

A floating ball valve uses a ball that is not fixed to the stem. The ball moves slightly toward the downstream seat under pressure, creating a tight seal.
A trunnion mounted ball valve uses additional supports to fix the ball, reducing operating torque.
