The IGWXDF3204Y bi-directional hard impact hard rotation ball valve is developed by combining the superior sealing performance of ball valves with the advantageous structure of butterfly valves. It has the superior bi-directional pressure bearing capability of fixed ball valves, can be used in liquid pipelines containing fine particles, and has practical advantages such as high operating temperature and long service life. Its essence is the combination of butterfly valve and half globe valve structure function, which is superior to half globe valve and fixed ball valve installation.

The sealing principle combines the front end sealing of the fixed ball valve with the forced sealing of the eccentric butterfly valve, thereby achieving bidirectional cutting of high and low inside the pipeline. When the water pump stops running and the outlet pressure of the pipeline is higher than the inlet pressure, using a rotary ball valve can effectively prevent backflow, which is a function that butterfly valves and half globe valves do not have. The rotary ball valve can be formed into gradient functional materials such as martensitic stainless steel, austenitic stainless steel, hard alloy, etc. using advanced processes such as supersonic plasma spraying and vacuum protection infiltration stack according to different hardness requirements on the sealing surfaces of the main and auxiliary parts. This valve, with its superior cost-effectiveness, is bound to bring about a revolution in pipeline network valves. It enables ordinary pipeline networks, especially water system pipelines, to enjoy the same high performance as high-end systems such as thermal power and gas at mid to low prices.
