The valve manufacturers use FEAsimulation tools to effectively optimize the design. This paper briefly explains the typical problems faced in the industry with the conventional globe such as the difficult manual operation due to higher valve torque, stem bending issues in stainless steel material, packing performance deterioration by rotating stem design, galling problems at stem threads and at flange bolts and gland packing eyebolts at low temperature. It also dealt on the common control valve parameters which degrade performance like cavitation problems leading to erosion, reduced flow capacity, flow separation & recirculation, pressure drop across the valve & Noise levels.
