A globe valve uses a linear motion for moving a disc closure member into or out of the seating surface. Globe Valves form a globular shaped cavity around the port region and hence the name. The disc can be of various shape and moves perpendicular to the globe valve seat.

This article is all about valves, and the various types of valves and fittings available. Valves are mechanical or electro-mechanical devices that are used to control the movement of liquids, gases, powders, etc. In most instances, valves rely on some form of mechanical barrier—a plate, a ball, a diaphragm, for example—that can be inserted and removed from the flow stream of the material passing by.

Comparison between Gate and Globe Valves, Cautions, Maintenance & Testing of Gate Valves

Apr 12, Posted by Bundor. Both gate and butterfly valves are two very common valves. The two have great differences in their own structure and usage methods, and in adapting to working conditions. This article will help users to better understand the difference between gate valve and butterfly valve, so as to better help users to select the valve.

Before explaining the difference between the gate valve and the butterfly valve, let's take a look at the respective definitions of the two. Maybe from the definition, you can find the difference between the two carefully.

Gate valves, as the name suggests, can cut off the medium in the pipeline like a gate. It is a valve that we use in production and life. The opening and closing part of the gate valve is called a gate, and the gate is used for lifting movement. The direction of movement of the shutter is perpendicular to the direction of flow of the medium in the fluid line. The gate valve is a kind of cut-off valve, which can only be fully open or fully closed, and the flow cannot be adjusted.

Butterfly valve, also known as flap valve. Its opening and closing member is a disc-shaped disc which is fixed on the valve stem and rotates around the stem valve shaft to open and close.

In addition, the butterfly valve itself does not have self-locking capability. It needs to install a turbine reducer on the valve stem. With it, the butterfly plate has self-locking capability and can also improve the operation performance of the butterfly valve.

Understand the definition of gate valve and butterfly valve, the following describes the difference between gate valve and butterfly valve:. In the above definition, we understand the difference between the movement direction and the movement mode of the gate valve and the butterfly valve. In addition, since the gate valve can only be fully open and fully closed, the flow resistance of the gate valve is smaller in the fully open state; In the fully open state, the thickness of the butterfly valve creates resistance to the flow medium.

The sealing performance of the gate valve is good, so it is often used in pipelines that require strict sealing and does not require frequent repeated switching, and is used to cut off the circulating medium. The gate valve cannot be used for regulating the flow rate. In addition, because the opening and closing speed of the gate valve is slow, it is not suitable for the pipeline that needs emergency shutoff. The use of butterfly valves is relatively more extensive, and the butterfly valve can not only be used for truncation, but also has the function of adjusting the flow rate.

In addition, the butterfly valve opens and closes quickly, and can also be frequently opened and closed, especially suitable for occasions requiring quick opening or cutting. Butterfly valves are smaller in size than gate valves and lighter than gate valves, so in some environments where installation space is limited, a more space-saving wafer type butterfly valve is recommended.

Among large-diameter valves, butterfly valves are the most used, and butterfly valves are also recommended for transporting medium pipes containing small particles of impurities.

Butterfly valves have gradually replaced other types of valves in many operating conditions, making them the first choice for many users. Under the same pressure and the same caliber, the price of the gate valve is higher than that of the butterfly valve. However, the diameter of the butterfly valve can be made very large, and the price of the large-diameter butterfly valve is not cheaper than the gate valve.

The difference in athletic ability In the above definition, we understand the difference between the movement direction and the movement mode of the gate valve and the butterfly valve. The difference between function and use The sealing performance of the gate valve is good, so it is often used in pipelines that require strict sealing and does not require frequent repeated switching, and is used to cut off the circulating medium. The difference in price Under the same pressure and the same caliber, the price of the gate valve is higher than that of the butterfly valve.

Globe valve

The gate valves are so called because the gate-shaped wedge inside is the most used, as well as the most abused, type of valve. Though designed to isolate or connect fluids, they are sometimes wrongly used for flow control. The gate valve should not be used for controlling the fluid flow or for throttling the flow as it can damage the valve due to the high velocity of fluid when the valve is only slightly open. They are normally used in applications where a minimum restriction to the flow of fluid is a design requirement and only an On-Off type of control is required. Normally the gate valves suffer from one common problem after long service and that is the valve becoming tight due to the deposition of silt on the guide ways. This type of complaint is common and is rectified by opening and cleaning the valve.

This article will help users to better understand the difference between gate valve and butterfly valve, so as to better help users to select the valve. Before explaining the difference between the gate valve and the butterfly valve, let's take a look at the respective definitions of the two.

Globe valves and gate valves are two of the most common valves in industrial plants. Both are designed to keep systems running as efficiently and safely as possible. These valves have similar bodies, but they feature their own unique designs and have their own applications. Contact The Valve Experts. Globe valves vs gate valves are designed for many applications in several fields, including the oil and gas industry. Globe valves are generally used to stop, start, and regulate flow within a pipe.


They offer more resistance to fluid flow, and have a high-pressure drop even when the.


Globe Valve: Parts, Types, Function, Symbol, Diagram, Advantages, and Disadvantages [With PDF]

Gate valves and globe valves are two of the most common valves used in industrial applications. Both contribute greatly to any industrial services. They may look alike but these valves function differently. In this article, you will know what makes the gate and globe individually unique as well as the major differences between the two valves. Gate valves are linear valves belonging to the shutoff valve family.

Both flow valves,Globe valve and gate valve have similar external housing but operational functions of both differ little. The main difference between globe and gate valve is in the form of the inner elements and the form of the flow inside the both valves. Globe valve has very good throttling ability while gate valve is not used for throttling.

Difference between Globe Valve and Gate Valve ?

A valve is used to control flow of liquids and gases. And ball, gate and globe valves are used to control flow of liquids. These valves in all forms are used to create waterways, and it is therefore essential to understand the differences and their uses.

There are countless types of valves for use across a variety of industries and applications. When it comes to flow control valves, valve types range from simple to sophisticated ; some valves are complex enough to adjust automatically to pressure and temperature variations. No matter their construction, flow control valves are designed to regulate the flow or pressure of fluids, and they typically react to signals generated by flow meters or temperature gauges.
