12 inch Ball Valve
Description
12 inch Ball Valves are normally trunnion ball valves, side entry ball valves or top entry ball valves; the design, manufacture and test are strictly according to API 6D/API 598 standard
What is 12″ Inch Ball Valve?
ZECO 12 inch ball valve can choose floating ball valve, trunnion mounted ball valve or top entry ball valve. As one of the only ball valve manufacturers in China with a history of nearly 30 years, ZECO, with the historical mission of continuous innovation and technological innovation, successfully sent the ball valve products of ZECO to one after another oil companies, offshore platforms and industrial projects, and was fully recognized by the owners. ZECO is dedicated to product performance research and development and product material research and development, and is committed to building an internationally renowned Chinese valve manufacturer.

Features of 12 Inch Ball Valve:
- ZECO 12 inch ball valve has metal-to-metal seat design. When ball valve is applied in the high abrasive or high temperature service, metal-to-metal seat shall be chosen;
- ZECO pays attention to the flow coefficient of the valve, because this is the index that measures valve current capacity, flow coefficient is bigger the pressure loss that shows medium flows through valve is smaller. ZECO will regularly test the flow coefficient of the newly developed products and old products of each series and each diameter to ensure that users will not incur extra costs due to the valve flow when using ZECO products;
- ZECO pays attention to the research of product materials, and will confirm the information needed by customers before confirming the order. The degree of pressure and temperature tolerance of the ball valve is not only related to the shell material, but also related to the seat, packing, gasket and other seals, seals can try polymer materials, graphite asbestos or rubber;Sealing material depends on the medium in the pipeline;
- ZECO 12 inch ball valve has the low emission control. Low emission packing is assembled whos max leaking rate of design and test stands at 100PPM.
