--- Modify the term "bonnet" is defined (see 3.2.2, GB/T 17213.1-1998 3.2.2);

--- Modify the definition of the term "trim" (see 3.2.4, GB/T 17213.1-1998 3.2.4);

--- Modify the definition of the term "holder" (see 3.3.2, GB/T 17213.1-1998 3.3.2);

--- Modify the term "nominal diameter" (see 4.1, GB/T 17213.1-1998 of 3.2.1.1);

--- Increasing the term "nominal pipe diameter" (see 4.3);

--- Increasing the term "rank" (see 4.4);

--- Modify the term "over-travel" (see 4.5.5, GB/T 17213.1-1998 4.1.5);

--- Delete the contents on Av flow coefficient (see 4.6, GB/T 17213.1-1998 4.2);

--- Remove the "basic equation to determine the flow coefficient" (see GB/T 17213.1-1998 4.2.1);

--- Remove the "flow coefficient Av" method of seeking (see GB/T 17213.1-1998 4.2.2);

--- Added "valve nominal diameter and nominal pipe diameter identical" requirement (see 4.6.1, GB/T 17213.1-1998 4.2.3);

--- Increasing the terms "mounted Flow Characteristics" (see 4.10);
