The single flange isolation and relief valve adopts an integrated structural design, with one end featuring flange connection for quick installation. It integrates dual functions of isolation and relief, offering easy operation and reliable sealing. Suitable for the front-end pipeline of pressure instruments or transmitters, it enables system isolation and safe medium discharge without stopping the machine. Widely used in industries such as petroleum, chemical, and power, it effectively enhances maintenance safety and system operational stability.
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.
The welded flange isolating valve combines the advantages of welding and flange connection. One end is welded and fixed to the main pipeline
The dual isolation and relief valve integrates two independent isolation valves and an intermediate relief port, achieving dual shutoff and safe discharge functions.
