The valve body, cover, stem, ball and other parts of stainless steel high temperature valve are made by cast or forged Cr-Ni Austenitic stainless steel 304, 304L, 316, 316L, 310S. Different materials can be applied to a variety of media such as water, steam, oil, acetic acid, urea and oxidizing media. Stainless steel offers excellent corrosion resistance and high temperature mechanical properties, has been widely used in chemical industry, aerospace industry heat control and nuclear fuel post-treatment equipment corrosion control components especially for the oxidation medium.
High temperature stainless steel ball valve is suitable for Class150 ~ 1500, PN1.6 ~ 16.0 MPa and working temperature from -40 to 650℃ to cut off or connect the medium in the pipeline system . With trunnion mounted and float operated is optional, PERFECT provides a complete line of stainless ball valve for sale that is supplied to high-temperature applications. Our factory provides 304, 304L, 316, 316L, 310S stainless steel high temperature ball valve for your choice. Please provide more information such as nominal size, nominal pressure, valve body material, interior material, medium temperature, flange standard, flange sealing surface for convenience that we can provide you with the customized service for you.
