The Construction, Types And Advantages Of Globe Control Valves

A globe control valve is a type of valve that is fundamentally used to control and regulate the flow of fluid inside a pipeline. The use of the word ‘globe’ in the name of this instrument is the because it has a spherical body shape in which the two halves of the body are separated with the help of an interior baffle. They are also sometimes called by the name of throttle valves.


As we have already discussed that the body shape of the globe control valves is that of a globe. Other components that it contains include:

  • Rising stems
  • Movable plug or any kind of rotatable disc element
  • A stationery spiral seat

Types of body designs

  • TEE pattern: Containing a Z-shaped diaphragm, this design is the most common body type of a globe valve. This type of globe valve body design is used in cases where the primary focus is throttling and pressure drop does not have much importance.
  • Angle pattern: In this type, the ends are given an angle of 90° and the fluid flow takes a 90-degree turn while flowing through the valve.
  • WYE pattern: The angle between the seat and stamp is somewhere near 45°, providing a straight path and allowing easy flow at the opening, resulting in the least resistance to fluid flow.


  • Cooling water systems: For the regulation of water flow around the system.
  • Fuel oil systems: Because here, water-tightness needs to be taken care of along with the flow.
  • Feedwater
  • Chemical feed
  • Condenser air extraction
  • Heated drains
  • Boiler drains and vents


  • The globe control valves are available in different designs that cater to different needs. These variety and variations in the body designs are of great help and serve diverse purposes in different fields.
  • They have a great shut off capability.
  • The seats of a globe control valve are extremely adjustable and easy to operate and resurface.
  • If you remove the disc from the stem, then you can use this valve as a stop check valve.

Lastly, the flow direction and pressure of the globe control valve can be adjusted according to the temperature. This means that when the temperature is low, there is more pressure under the disc. This aids in providing easy operation and also protects the equipment. However, if the temperature is high in the steam service, then pressure is shifted to above the disc. This is done so that the stem does not undergo contraction when it is cooled.

One of the best and quickest ways to achieve a smooth wood is through electric sanders. Sander is a power tool which is used to smoothen a certain surface by scratching through sandpaper. They are usually powered by electricity, and it’s used with the help of a hand. There are different types of electrical sanders; in this article, we will cover a random orbital sander review.

In this review, you will able to distinguish the best random orbital sander that fits your preferences and needs.  This random orbital sander review aims to help users of electrical sanders in choosing the right power tool for them. Each orbital sander has its distinction and negative feedbacks. However, all these items provide efficient workbench.

List of Orbital Sanders and their features

Black and Decker BDERO100 Orbital Sander

This random orbital sander is perfectly fit for home jobs or small activities. It’s quite not heavy, it weighs 3.16 pounds, and it’s considered one of the lightest sanders available in the market. It’s easy to use, and you can move smoothly in any certain surfaces you wish to.

This orbital sander has a spin rate of 12,000 OPM, and it suited on small-time sanding jobs only. Even though it’s just applicable to light jobs, it gives an efficient finish output upon usage. This orbital sander has a small dust pot and comes with a 2-year warranty.

DWE6421K DeWalt orbital sander kit

This random orbital sander showcases a 12,000 OPM, and it weighs 4 pounds. This unit comes with a comfortable handle, and it’s easy to use. It comes with a Velcro attachment system which makes easier for the user to change the sanding pad.

It’s manufactured by DeWalt, and it can prevent dust from getting inside the orbit sander. The unit’s covered with rubber especially on important parts of the unit. This unit’s vigorous and very sturdy.

Upon purchase, DeWalt comes with a nice package including a manual, dust collecting pad, the orbital sander, and a pleasant carrying bag. The company offers 3 years of warranty.

ROS20VSC Bosch orbital sander

This is one of the most advanced orbital sanders which present great and functional features. It showcases wonderful design, and it’s easy to manage. This unit can spin up to 12,000 OPM, but it can be managed to lower it down to 7,500 OPM. When you’re doing sanding, it’s best that when you’re finishing the surface, you minimize the spinning ability of the orbital sander to achieve a good and excellent finish.

The Bosch orbital sander comes with an advanced dust collecting system located at the back of the unit. It also features a micro-filter system making it filter as little as the 0.5 microns in diameter. It also has pad dampening feature.

This unit’s known for its Hooktight sanding pad attachment system which holds the sander a great grasp. It has a total of 35,000 hooks to avoid unnecessary accidents while performing sanding jobs. This unit comes with a nice case and a 1-year warranty.
