1, three eccentric multi-layer metal butterfly valve butterfly valve seal for the hard and soft laminated metal sheet, with a metal seal and elastic seal dual advantages, both in the case of low temperature and high temperature, have excellent sealing performance. 2, the use of three-dimensional eccentric structure, the valve seat and the disc almost no friction, when the valve is closed inside almost no damage to parts; This structure greatly improves the performance of the valve in use. And the closer the more tight the sealing function. 3, in the upper and lower parts of the valve stem with bushings, and each bush wear and friction resistance is very small, this structure can completely prevent wear and adhesion, but also improve the service life. 4, the valve body sealing surface, the use of surfacing alloy steel or Stanley Cemented Carbide, sealing surface wear resistance, erosion resistance, corrosion resistance; long service life. 5, unique structure, small switching torque, flexible operation, labor-saving, convenient, high and low pressure from the media, sealing performance and reliable. Can be used for hoist and adjustment equipment. This keyword search: Yongnian Innot Valve Co., Ltd. butterfly valve supply information
