Meaning of additional models for high-pressure gate valves
Thread Content
My unit is for wax oil hydrocracking. The three-way control valve associated with the new hydrogen generator has experienced multiple weld leaks, so I plan to order a new valve. The valve should meet American standards, but there are some differences from those standards. Please take a look at the pictures: Z (gate valve), 8 (pressure rating of 1500 LB), 8 (structural type PS-BG-OS), S (connection method: socket welding), 9P-H1 (material: A105), 02 (valve core material: STE, STE, 13%Cr). I’m not sure what the 9P in Z88S9P-HI02 means; could anyone among you who knows answer this question?
Z88S (manual) 9P (with a 150mm pipe at each end of the valve/EACH END WITH A 150MM SHORT PIPE) – HI02; any other interpretation is correct.
Great! I’ve been guessing it’s an extended tube, but I haven’t found any relevant standards

Hai Chuan really has a lot of experts; I’ve learned from them.
This model numbering is simply absurd; you might as well call the manufacturer directly
P denotes that there is a 150mm long pipe at each end of the valve/EACH END WITH A 150MM SHORT PIPE; S9 is integrated, indicating that the wall thickness of the short pipe is SCH160. This coding system is the coding rule of Luoyang Institute.
