Trunnion Ball Valve - API6D, Full Bore & Reduced Bore
Tengs Valve supplies high-quality Trunnion Ball Valves in full bore and reduced bore designs, available in 2-piece and 3-piece split body configurations. The fixed ball valves are fabricated from cast or forged carbon steel and stainless steel, with flanged (RF, RTJ) or BW ends connections, and are operated by lever or gearbox. Manufactured to API6D, ANSI, and DIN standards. Ideal for high-pressure oil & gas, chemical, and power generation applications requiring reliable shut-off and low operating torque.
