What is a globe valve and what are its characteristics?

A globe valve has a linear motion plug that moves perpendicular to the seat to control flow. The body is spherical (globe-shaped) with an S-shaped flow path. Characteristics: excellent throttling capability, tight shutoff, available in various trim designs (plug, cage, characterized). Flow direction through the valve affects performance - flow under plug is quieter but has higher shutoff force. Globe valves are the most common control valve type, suitable for wide range of applications but cause higher pressure drop than some alternatives.
