We have bal valves of full and reduced bore to meet users' different needs.full brod ball valves have the same inside diameter as that of pipeline.with the lowest fluid resistance for the convenience of cleaning the pipeline.while reduced-bore ball valves weighs only 70% of the full-bore ball valve with the same caliber,a saver of cost and price,and its fluid resistance coefficient is only 1/7 of that of the globe valve with the same caliber,so that reduced-bore valves are widely used abroad.
