Wholesale Flanged Swing Type Check Valve CF8 Material Suppliers, Manufacturer
Product Description
Technical Specifications
Characteristics
Core components such as valve body, valve disc, rocker, etc. are preferably made of 304 stainless steel, 316 stainless steel, 316L stainless steel, or duplex stainless steel materials.
Key Advantages
The dense passivation film formed on the surface can resist the erosion of weak acids, weak bases, salt spray, seawater, and organic solvents. Compared with cast iron and cast steel valves, it can effectively avoid problems such as valve body corrosion and medium pollution, and is suitable for complex corrosion conditions.
The tensile strength of stainless steel material is ≥ 520MPa, and its mechanical properties are stable in the temperature range of -40 ℃~600 ℃. It can withstand the impact of high-pressure media and long-term erosion of high-temperature media, and is not easily deformed or cracked.
316L stainless steel and other materials have high surface smoothness, no pores, and do not adsorb impurities, meeting the hygiene standards of industries such as food, pharmaceuticals, and drinking water, and will not cause secondary pollution to the medium.
Application Scenarios
Widely used in pipeline systems in industries such as chemical, petroleum refining, marine engineering, pharmaceuticals, food and beverage, electricity, water treatment, etc., it is particularly suitable for conveying corrosive media, high-temperature and high-pressure media, and clean fluids, such as chemical raw material conveying pipelines, boiler steam pipelines, seawater desalination systems, pharmaceutical process pipelines, etc.
