What is Globe Valve?
A globe valve is a linear motion valve used to stop, start, and regulate the fluid flow.
The globe valve disk can be removed entirely from the flow path, or it can completely close the flow path.
During the opening and closing of the valve, the disc moves perpendicularly to the seat.
This movement creates the annular space between the disk and seat ring that gradually closes as the valve closed.
This characteristic provides the globe valve good throttling ability required for regulating the flow.
Leakage from the globe valve seat is less as compared to the gate valve, mainly due to right angle contact between
the disc and seat ring, which allows tighter seal between seat the disk.

A Globe valves is a linear motion valve and are primarily designed to stop, start and regulate flow.
The disk of a Globe valve can be totally removed from the flowpath or it can completely close the flowpath.
Conventional Globe valves may be used for isolation and throttling services. Although these valves exhibit slightly
higher pressure drops than straight=through valves (e.g., gate, plug, ball, etc.), they may be used where the pressure
drop through the valve is not a controlling factor.
Because the entire system pressure exerted on the disc is transferred to the valve stem, the practical size limit for these
valves is NPS 12 (DN 300). Globe valves larger than NPS 12 (DN 300) are an exception rather than the rule. Larger
valves would require that enormous forces be exerted on the stem to open or close the valve under pressure. Globe
valves in sizes up to NPS 48 (DN 1200) have been manufactured and used.
Globe valves are extensively employed to control flow. The range of flow control, pressure drop, and duty must be
considered in the design of the valve to avert premature failure and to assure satisfactory service. Valves subjected
to high-differential pressure-throttling service require specially designed valve trim.
Generally the maximum differential pressure across the valve disc should not exceed 20 percent of the maximum
upstream pressure or 200 psi (1380 kPa), whichever is less. Valves with special trim may be designed for applications
exceeding these differential pressure limits.
