Structural features

H74F46 Wafer type single-valve fluorine-lined check valve is an automatic valve that relies on the flow of the medium itself, and the automatic opening and closing flaps are used to prevent the medium from flowing in the reverse direction. It is suitable for opening and closing devices in various industrial piping systems with strong corrosive media. Due to the unique performance of fluoroplastics in the resistance to strong corrosive media, the lining is lined on the inner walls of valve bodies or pipe fittings of various cast iron, carbon steel, and stainless steel, and on the outer surfaces of valve inner fittings. Not only can it adapt to the strong corrosive medium under different working conditions, but also it can replace expensive rare metals. Its corrosion resistance life is about 10-20 times longer than that of ordinary valves.

Scope of application

Widely used in petroleum, chemical industry, power station, chemical fiber, urban construction, railway, military scientific research, pharmaceutical, environmental protection, metallurgy, building water supply and drainage engineering, fire protection system, papermaking, mining, tap water, farmland water conservancy, chemical fertilizer and other industries.
