JB/T 2001.25-1999 This standard is a revision of JB 2025-84 "Type and size of distribution valve core for hydraulic press (Pg=200×100000~315×100000Pa)". This standard specifies the type, size and technical requirements of the distribution valve core. This standard is applicable to distribution valve cores for various hydraulic presses with nominal pressure of 20, 31.5MPa and emulsion or oil as medium. It is not applicable to special fast free forging presses. This standard was first issued on January 1, 1984.
