Product overview

The bidirectional, hard-to-fight, rotating ball valve combines the superior sealing performance of a ball valve with the advantageous structure of a butterfly valve. It offers the advantages of a trunnion-mounted ball valve, including bidirectional pressure-bearing performance, compatibility with fine-particle liquid pipelines, and practical advantages such as high operating temperatures and a long service life. It essentially combines the structural functions of a butterfly valve and a semi-ball valve, offering installation advantages over semi-ball valves and fixed-ball valves. Its sealing principle combines the front-end seal of a trunnion-mounted ball valve with the forced seal of an eccentric butterfly valve, achieving bidirectional high-low isolation within the pipe. If the pump stops and the outlet pressure exceeds the inlet pressure, the rotating ball valve effectively prevents backflow, a feature not available in butterfly valves or semi-ball valves. The rotating ball valve can be fabricated on both the main and auxiliary sealing surfaces using advanced processes such as supersonic plasma spraying and vacuum-protected infiltration and lamination to achieve varying hardness levels using gradient materials such as cast iron stainless steel, austenitic stainless steel, and cemented carbide. With its superior cost-effectiveness, this valve is bound to revolutionize pipe network valves. It will make it possible for ordinary pipe networks, especially water systems, to enjoy the same high-performance and high-quality products as high-end systems such as thermal power and gas systems at a mid-range price.
