Product Description
Product overview Two-way flow head-to-head rotary ball valve one by one is developed by combining the superior sealing performance of the ball valve with the superior structure of the butterfly valve. It has the superior two-way pressure bearing of the fixed ball valve, can be used in liquid pipelines containing fine particles, etc., and has practical advantages such as high operating temperature and long life.Its essence is the combination of the structure and function of the butterfly valve and the fixed hemispherical valve, and the installation is superior to that of the hemispherical valve and the fixed ball valve.The sealing principle combines the front-end sealing of the fixed ball valve with the forced sealing of the eccentric butterfly valve, so as to achieve a two-way high and low cut-off in the pipeline.When the water pump stops running and the outlet pressure of the pipeline is higher than the inlet pressure, the use of rotary ball valves can effectively prevent the backwater from flowing back, which is also a function that butterfly valves and hemispherical valves do not have.The rotary ball valve can use advanced processes such as supersonic plasma spraying and vacuum protection seepage stacking to form gradient functional materials such as martensitic stainless steel, austenitic stainless steel, and cemented carbide on the two sealing surfaces of the front and rear according to different hardness requirements. Functional materials such as martensitic stainless steel, austenitic stainless steel, and cemented carbide.With its superior price/performance ratio, the valve makes it a reality that ordinary pipe networks, especially water system pipe networks, can also enjoy the same high-performance and high-quality products of high-end systems such as thermal power and gas at medium and low-end prices!Product features1.It is convenient to open and close quickly, labor-saving, low fluid resistance, and can withstand pressure in both directions.
2.The structure is simple, the dimensions are small, the structure length is short, the size is small, and the weight is light. It is suitable for large-caliber valves.
3.The seal is tight, the double eccentric metal is hard sealed, and the fouling does not affect the opening and closing.
4.There is no friction on the sealing surface during normal opening and closing.
5.It has a long service life, wear-resistant sealing surface, and has a compensation function. Product Parameters
