Globe Valves

Curtiss-Wright 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.

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.

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 & 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 APPLICATIONS

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. 

Benefits:

  • Simple structure and lightweight design.
  • Easy to operate with a quick response to open and close.
  • Convenient maintenance, disassembly, and replacement if needed.
  • Wide range of applications.
  • Small fluid resistance.
  • Tight and reliable design to ensure proper sealing.
  • Resilient performance from arduous media.
  • Ensures it’s always operational and efficient.

Electric Globe Valve 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. 

  • Large mixing and diverting circuits
  • Air handling units.
  • Chillers.
  • District heating appliances
  • Constant and variable flow circuits
  • Cooling water systems.
  • Fuel oil systems.
  • Feedwater or chemical feed systems.
  • 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.

 

Benefits:

  • Rugged and suited to high-force applications.
  • They can produce forces 25 times that of a pneumatic valve.
  • Operate pressures up to 4,000 psi.
  • Minimal loss of power when pumps and motors are spaced apart.
  • Hold torque constant without a pump constantly supplying fluid.
  • Easy to maintain. 
  • Accurate and efficient.

Hydraulic Globe Valve Applications

Hydraulic globe valves suited a range of applications where high force and torque are required, including:

 
  • Hydraulic fluid power systems
  • Construction machines
  • Stationary systems - balers/presses

What is a hydraulic operated valve?

A hydraulic operated valve is a mechanical device used to regulate fluid flow with a hydraulic system/circuit. They are used to shut off the flow, redirect flow or control the flow level to a specific area.


FAQ

How does a globe valve work?

A globe valve is used for throttling flow control and is often used for on-off service. The fluid shut-off is achieved by moving the disc against the flow stream, and the flow pattern involves changes in direction, resulting in greater resistance to flow, causing a high-pressure drop.

 

What is a high pressure globe valve?

A high-pressure globe valve is a globe valve designed to handle high-pressure and high-temperature applications, making it a popular valve option in nuclear plants.

What is the difference between a gate valve and a globe valve?

A gate valve shuts off flow by moving the disc across the flow stream, it can be installed in various directions, but it can’t regulate the flow level.
A globe valve shuts off flow by moving the disc against the flow stream; it regulates flow but can only be installed in one direction. 

 

Are globe valves directional?

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.

  • For low temperature and pressure applications, globe valves are usually installed so that pressure is under the disk. 
  • For high temperature and pressure applications, such as steam, globe valves are installed so that pressure is above the disk.
