Globe style control valves
Globe style control valves are the most common type of control valve. They got their name because in the early design of the valve the interior cavity of the valve had a circular or globe shape. Globe valves are also known as Linear Valves because the stem that actuates the valve moves up and down in a straight line.
Globe Valve features and design
Globe style control valves differ significantly from rotary valves such as ball, eccentric plug and butterfly valves in that they have a “torturous” flow path. The flow changes direction several times as it passes through the valve regardless of the stem travel. This torturous path acts to dissipate energy due to friction which in turn makes the globe valve less susceptible to noise and cavitation problems.
Another benefit to the globe valve design is that it can control extremely low Cv’s/Kv’s.
Globe valves are versatile and suitable for many different applications
Globe style control valves are available with specialized trim that allows them to handle very high pressure drops of both liquids and gases.
Globe valves come in sizes ranging from ¼” up to 20” with sizes ½” through 8.0” being the most common. There is also a great variety of flow characteristics which allow them to be used in many different applications.

The Model 2266 is an inexpensive globe-style control valve for plant utility and process applications. It incorporates linear control characteristic for smooth throttling action on pressure, temperature and liquid level control. The TFE seat provides reliable shut-off for on-off applications. Sizes are1/2″, 3/4″, 1″, 1-1/2″ and 2″ (DN15, 20, 25, 40 and 50).
The Cashco Model 521 is a sliding stem, globe style, bellows sealed, pneumatically actuated control valve designed to provide superior long-term performance and maximum corrosion resistance in pure chemical service. The design allows for all wetted internal parts to be machined from a solid block of isostatically compacted, virgin TFE, thus ensuring maximum density and the lowest possible permeability. An additional design benefit is that the wall thickness integrity is ensured as a result of the TFE body being internally machined after it is secured in a cast 304 SST body shell, thus preventing distortion problems related to the plastic stability of TFE. There is simply no better design or materials available when consideration is given to corrosion resistance and thermal stability.
This series of valves is especially suited for the harsh demands of certain process industries. These valves are designed for modulating control of liquids, vapors and gases in industrial applications where performance, quality and small physical size are important.
The rugged, corrosion-resistant construction offers features and performance normally found in more expensive designs. The compact, high performance, all-steel actuator, along with standard body assembly construction of stainless steel, is designed to provide years of service and simple easy maintenance. A few more standard features include: adjustable spring preload, adjustable travel stop, heavy body cross section and replaceable seals on all reduced innervalves.
