Globe valve is a linear motion type of valves and is typically used in both on-off and throttling applications. In globe valves, the flow of the fluid through valve follows an S-path. Due to this, the flow direction changes twice which results in higher pressure drops. Due to other advantages offered by them, they are widely used in applications where pressure drop through the valve is not a controlling factor.
These valves are generally not used beyond sizes larger than NPS 12, (which is 12”) DN 300, as enormous forces are exerted on the stem to open or close the valve under fluid pressures. Globe valves require high pressures on the seat to keep it closed when the fluid exerts pressure from the bottom of the disc. They are used for both on-off and throttling applications, but special types of trims are required for throttling applications where large pressure drops are involved.
