Globe Valves

Daume Valves Division offers a wide range of globe valves in a variety of construction materials, showcasing a variety of versatility and adjustment to suit a diverse set of specifications. 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.

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.

GLOBE VALVES: PURPOSE & FUNCTIONALITY

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

Features and Benefits

Easy maintenance and repair
Good shutoff capability
Shorter stem travel
Available in a variety of patterns
Good throttling capability
It can be used as a stop check valve

Globe Valve Applicaitons

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:

Cooling water systems
Fuel oil systems
Boiler vents and drains
Turbine seals and drains

TYPES OF GLOBE VALVES

Globe valves come in a variety of body patterns, but the primary three types include standard, angle, and oblique.

Standard Pattern Globe Valve

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.

Angle Pattern Globe Valve

An angle pattern globe valve features a 90-degree angle at the ends. This unique design means that angle pattern globe valves are functional in applications that have pulsating flow. It’s highly advantageous when mounting near a pipe bend; the angle design reduces the flow resistance and reduces the number of pipe joints and elbows.

Oblique Pattern Globe Valve

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.

ELECTRIC GLOBE VALVE

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.

Marine environments.

HYDRAULIC GLOBE VALVE

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.
