With the spool and seat sealing ring formed together sealed, can effectively withstand the media pressureThe material of the valve body is made of different metal materials according to different process mediaCommonly used materials are: cast iron, cast steel, stainless steel, carbon steel and so on
Medium and low pressure valve body, usually casting process to produce valve bodyMedium and high pressure valves are manufactured by forging process
valve bodyEnglish: valve body.It is a main component in the valve. There are different mechanical methods according to the pressure grade, such as casting, forging and so on
