600LB A351-CF8 Metal Seat Flange Rising Stem Stainless Steel Gate Valve
API600 standard stainless steel gate valve with handlewheel order export to UAE for oil pipeline installation. This size is 6'' , all use handlewheel operated, from 14'' and bigger size, we suggest to use bevel gear for easy open and close. This type is metal seat, rising stem, non-rising stem is also available. Metal seat temperature range from -196 degree to 425 degree. But for -196 degree, we will suggest to use other materials and parts. And stainless steel A351-CF8 is a kind of anti-corrosion material, and we also have alloy steel, duplex steel for more anti-corrosion materials to choose.
Our engineer team will give you the best suggestion for your application.
