Globe valves are designed to stop, start, and regulate flow within a pipeline, by means of throttling and isolation. These types of valves can be used in application with marine ballast systems, as well as heating and air conditioning, water distribution and/or treatment, and much more.
Curtiss-Wright's Globe Valves come from its Phönix and Strack valve group manufacturing product brands, both of whom pride themselves in providing high quality, reliable valves and equipment. Our globe valves feature the three typical body designs: Tee, Angle, and Wye pattern, and we also supply electric, hydraulic, and more, types of valve actuators to suit every industrial requirement.
A globe valve can stop, start and regulate flow in a pipeline. The valve is shaped like a sphere and includes a stem that moves up and down, a disc, and a seat. It works by the disc lowering or raising through the valve stem. When the disc lowers, the flow pattern shuts off; if the disc increases to maximum, the flow runs at maximum too. If the disc raises to less than maximum, the flow regulates in proportion to the vertical disc position. The flow inside a globe valve changes in direction, causing greater resistance and high pressure to drop
Globe valves work in a variety of applications, dependent on the purpose and raw materials used. They are reliable in high temperature and pressure services, to regulate steam and condensate, and even in nuclear plants.
They can also apply in these other disciplines:
Globe valves come in a variety of body patterns, but the primary three types include standard, angle, and oblique.
The most common of the three, it's used in throttling services such as around a control valve by allowing the stem and disk to move at an angle towards the fluid’s direction.

In an oblique pattern globe valve, the seat and stem measure at approximately 45 degrees. Giving a more direct path at full opening and also offering the least resistance to flow. They are a suitable alternative for a high-pressure drop application.
An electric globe valve is a valve that features an electric actuator driving the stem up and down. It changes the distance between the disc and the seat to achieve opening and closing and is mainly used in cut-off applications. An electric cut-off valve is primarily used to gain precise control in demanding hot and cold water applications, including steam and compressed air applications.
Curtiss Wright Valve Division offers a selection of globe valves that suit various applications. Here are some of the more common placements for electric actuated globe valves.
A hydraulic globe valve uses hydraulic fluid to power the stem and allows it to move up and down to control the flow rate. They can be used to completely shut off the flow, redirect pressurized fluid, or control the level of flow.
Hydraulic globe valves are quick to respond but are not ideal for environments under high pressures, as gas is compressible. Hydraulic globe valves are designed to be cost-effective in a compact assembly, providing a highly accurate flow-versus-stroke characteristic.
Hydraulic globe valves suited a range of applications where high force and torque are required, including:
A Globe valve has specific flow directions; the disc will close against or in the same direction of fluid flow. Depending on the application, flow pressure, and flow temperature, fluid will be above or below the disc.
