Globe Valve Advantages: 6 Things You Should Know

Why should you choose globe valves over other types of valves? Because they are easier to operate and maintain, have a lower leakage rate, and are functional in a wider range of applications. Globe valves are also less likely to clog than other types of valves.

A variety of industries use globe valves, including oil and gas, chemical, power generation, and water treatment. They are also beneficial in a variety of applications, such as regulating flow, controlling pressure, and managing temperature. Read on to learn more about globe valve advantages and why you should choose them.

1. What Are Globe Valves?

A globe valve is a type of valve that regulates flow by using a movable disk to open and close off an exit port. The disk connects to a stem, which a handle or lever operates. Globe valves get their name from their spherical shape.

Globe valves are useful for regulating flow, controlling pressure, and managing temperature in a variety of different applications. Not only are globe valves easier to operate and maintain than other types of valves, but they also have a lower leakage rate. This makes them functional in a wider range of applications.

2. How Does a Globe Valve Work?

A globe valve is a device whose primary function is to open and close members (valves) that are driven by stems. These valves lift along a surface called the valve seat in order to achieve linear movement.

The typical globe valve operates by using various components that work together (i.e. handwheel, stem, valve body and cover, closure, and packing assembly). The handwheel connects to the valve stem, which in turn drives the valve flap. This reciprocal motion along the direction of the valve seat axis opens or closes the pipeline when it needs to.

Globe valves are widely used and are generally produced in smaller diameters up to DN400 (NPS 16). Larger diameter specifications are only for special pipelines. For example, a large oxygen pipeline may require a large-diameter stainless steel globe valve This is due to the existence of other valves that may cause friction and lead to static fires.

3. Advantages of Globe Valves

There are many advantages of globe valves over other types of valves. These advantages include:

Ease of Operation

Globe valves are easy to operate because they only require a quarter turn to open or close. A Handle or a lever attached to the stem opens or closes the valve This makes them ideal for applications where quick operation is necessary, such as in emergency situations.

Maintainability

Operating and maintaining a globe valve is easier than other types of valves. Globe valves have a simple design and few moving parts, which makes them less likely to break down.

Leakage Rate

Globe valves have a lower leakage rate than other types of valves. This is because the disk in a globe valve seats more snugly against the port, which creates a tighter seal.

Versatility

Unlike other types of valves, globe valves are adaptable and can function in a wider range of settings. This is due to the different sizes, materials, and pressure ratings that they come in.

Clog Resistance

Globe valves are less likely to clog than other types of valves. This is because the disk in a globe valve can be easily removed for cleaning.

Long Service Life

They have a long service life of up to 20 years with proper maintenance. They can withstand high pressures and temperatures.

Contamination Resistant

Their design makes them resistant to contamination and fouling. They control fluid flow in a variety of applications, such as regulating pressure, managing temperature, and controlling the level of a liquid.

They are also cost-effective and can save you money in the long run.

4. Applications of Globe Valves

Globe valves are beneficial in regulating flow, controlling pressure, and managing temperature. They find use in industries such as oil and gas, chemical, power generation, and water treatment.

Some common applications of globe valves include:

Regulating Flow

Globe valves regulate flow in piping systems. They go in the line between a pump and a tank or reservoir. The valve opens to allow flow from the pump to fill the tank, and then closes when the desired level is reached.

Controlling Pressure

Globe valves fit in the line between a pump and a tank or reservoir. The valve allows flow from the pump to fill the tank and then closes once it achieves the desired pressure.

Managing Temperature

Globe valves are installed in the line between a heat source and a heat exchanger. The valves’ opening and closing allow flow from the heat source to enter the exchanger which controls the temperature levels.

5. Industry uses

The oil and gas industry uses globe valves to regulate flow in pipelines. They install them in the line between a pump and a tank or reservoir. The opening and closing of the valve regulate the levels of the liquid.

Chemical Industry

In the chemical industry, globe valves function to regulate the flow of corrosive and toxic fluids. Their installation in the line between the pump and storage tank allows for precise control of dangerous chemicals.

Power Generation

The power generation industry uses globe valves to manage the temperature in piping systems. They are installed in the line between a heat source and a heat exchanger. The valve opens to allow heat from the source to enter the exchanger, and then it closes once the desired temperature is met.

Water Treatment Industry

Globe valves are used in the water treatment industry to regulate flow in pipelines. They are installed in the line between a pump and a tank or reservoir. The valve does this by opening to fill the tank and closing when it is at the desired levels.

Drip Applications

Globe valves are often used in drip irrigation systems. They situate between the water source and emitters, where they open and close to regulate how much water flows through.

Benefit from the Many Globe Valve Advantages

Globe valve advantages are many and varied. Their ability to withstand high temperatures and pressures, resist corrosion and contamination and regulate flow make them an ideal choice for a variety of industries. When you need precise control over liquids, globe valves should be your go-to choice.
