May I ask what is the standard number for valves in the Petrochemical Standards (SH/T) series?

As the title suggests, I’m asking what are the standard numbers for valves in the petrochemical standards (SH/T) series? I found this standard online: SH/T3064-2003; SH/T 3064-2003 – Selection, inspection, and acceptance of general steel valves used in the petroleum and chemical industry； In other words, what standard of valves correspond to the flanges specified in SH/T3406-2013?
Standard number: SH/T 3064-2003. Standard status: Revoked. English name: Specification for selection, inspection and acceptance of steel valves used in petrochemical industry. Standard status: Revoked. What is the replacement standard? Alternative: Alternative to SH 3064-1994; Announcement: Announcement by the Ministry of Industry and Information Technology of the People’s Republic of China, 2017 (No. 23). What is the classification for winning bids? Bid classification: Construction >> Raw material industry and communication, broadcasting projects >> P72 Petrochemical and chemical engineering. What is the ICS classification? ICS Classification: Fluid Systems and General Components >> 23.060 Valves. Issuing Authority: National Development and Reform Commission of the People’s Republic of China. Date of issuance: 2004-03-10. Date of implementation: 2004-07-01. Date of abolition: 2017-05-12. What is an authorized agency? Responsible department: Engineering Construction Management Department of Sinopec Group Company; Drafting unit: Sinopec Engineering Construction Company; Drafters: Zhao Yong, Ke Songlin, Zhang Baojiang; Approval number: J326-2004; Number of pages: 22; Publisher: Sinopec Press; Publication date: 2004-07-01
In other words, there is no corresponding valve standard for flanges in SH/T3406-2013.
Are API standard valves the same as those meeting US standards?
The petrochemical industry cannot create an independent flange system; upon checking SH/T 3406-2013, it is clear that it belongs to the American system. API stands for the American Petroleum Institute. What is the purpose of API standards? In fact, there is no need to emphasize the use of API valves; the national standard valve specification GB/T 12224-2015 also covers the American system, and it is sufficient to specify that it is a flange meeting American standard class requirements when making a purchase. With SH/T 3406-2013 being revoked, you can use the HG/T 20615-2009 flanges for the chemical industry; by comparing the flange dimensions of these two standards, you will understand the difference. Domestic standards are all based on the European system PN and the American system class.
You might want to take a look to see if it’s helpful: Compilation of Industrial Valve Standards (2016 edition)
It should be HG/T20592; be careful to distinguish between the European system PN and the American system class.
HG/T20592 corresponds to the PN system in Europe, while HG/T20615 corresponds to the class system in the Americas.
