Welded flange isolating valves combine the advantages of welding and flange connections. One end is welded and fixed to the main pipeline, while the other end features a flange for easy disassembly and maintenance. They are suitable for working conditions requiring high pressure, high temperature, or high sealing. The valve body is mostly made of carbon steel or stainless steel, featuring a sturdy structure, reliable sealing, and flexible opening and closing. They are widely used in industrial systems such as petroleum, chemical, power, and natural gas industries, serving to safely isolate instruments or equipment and ensure operational safety and stable system operation.
The single flange isolation and relief valve adopts an integrated structural design, with one end featuring a flange connection for quick installation.
The stainless steel welded flange isolating valve is made of 316 or 304 stainless steel, combining high sealing performance at the welded end and convenient disassembly at the flange end.
