F Ball Valve

Forged Ball Valve

Forged Ball Valves are designed and manufactured in accordance with latest international standards like API 6D, API 608 and BS 5351 to provide highest safety, efficiency and accuracy.

The “INVENT” Ball Valves are economically priced and designed to last. These Valves provide exceptional performance in even the most stringent applications found in the Oil & Gas industry and other industries. We offer a wide range of elective seat and seal materials.

We are Manufacturing Forged Ball Valves in Single Piece; Two-Piece & Three-Piece cast steel constructions. These Valves are manufactured to the highest possible quality standard. Many of our threaded and socket weld Ball Valves are manufactured according to the ASME B16.34 design standard. These valves provide the exceptional performance in even the most stringent applications found in the Oil & Gas industry and other industries. We manufacture high quality Trunnion mounted Ball Valve which are manufactured under, for more information contact us right now.
