Main advantages: 1. German standard lifting check valve is an automatic sealing valve. The valve automatically opens and closes the disc depending on the flow of the medium itself, effectively preventing the backflow of the medium; 2. Disc with stainless steel spring device, the valve can be installed horizontally or vertically; 3. Surfacing welding CO hard alloy on the sealing surface, featuring wear resistance, corrosion resistance, friction resistance and long service life; 4. Reasonable product structure, reliable sealing, excellent performance, beautiful appearance; Application: hot oil system, steam system, cold and hot water system.
