How to use Globe Valve?

A globe valve is a type of valve used to stop, regulate, or start the flow of liquids and gases through a pipeline. It's called "globe" because its body's shape resembles a globe or a sphere. It's made up of three components: the body, the plug or disk, and the stem.

The disk moves up or down inside the valve's body, opening or closing the valve and controlling the flow. This movement is made possible by the stem, which connects the hand wheel or actuator outside the valve to the disk inside.

What Are the Types of Globe Valve?

There are two types of globe valve - the stop valve and the regulating valve. A stop valve is used to open or close the flow of fluid completely. It means that it is either fully open or fully closed and has no means of regulating the flow.

A regulating valve, on the other hand, is designed to regulate the flow of the fluid. It means that it can be partially open or partially closed, allowing for more precise control over the flow of liquid or gas through the pipeline.

How to Use a Globe Valve?

Using a globe valve is relatively simple and straightforward. Here's how to use it:

Step 1: Check if the valve is in the correct position. If the valve stem is parallel to the pipe, then the valve is open, and fluid or gas can pass through. If it's perpendicular to the pipe, then the valve is closed, and no fluid can get through.

Step 2: Turn the hand wheel or actuator counterclockwise to open the valve. It allows the fluid or gas to flow through the pipeline.

Step 3: If you need to regulate the flow, adjust the hand wheel or actuator by turning it clockwise or counterclockwise. It controls the disk's position, allowing more or less fluid to pass through the pipeline.

Step 4: To close the valve, turn the hand wheel or actuator clockwise. It will move the disk back up, blocking the flow of liquid or gas in the pipeline.

Final Thoughts

Whether you're working in oil and gas, water treatment, or any other industry that requires a fluid system, it's essential to know how to use a globe valve effectively. From stop valves to regulating valves, knowing the valve's types and functions can mean the difference between a smooth operation and disaster.
