PR2 gate valve is mainly used in the PR2 class wellhead and X-mas tree. It controls the opening and closing of fluid in the production process and is one of the core components of the wellhead and X-mas tree. However, PR2 class wellhead and X-mas tree with high pressure are always the disadvantage of Chinese oil wellhead equipment manufacturers due to their high design, manufacturing and test requirements. After two years of development and testing, sanJack gate valves have finally passed PR2 validation.
