32 Design Basis Valve Stem Thrust F Stem

For rising-stem valves Equation 3-1 Where . F stem total stem load . F pack stem packing load . F stem rej stem rejection load P up A stem. Note the sign for the stem rejection load. This appears because the stem rejection load is always out of the valve body, thus it resists closure and assists opening. 3.2.1 Gate Valve Stem Thrust
