When comparing ball valves with gate valves, some differences may be glaring. For instance, gate valves need more than a full 360 degrees to shut off, while ball valves close instantly with a quarter-turn. Best way to find the industrial valve.
Additionally, ball valves have a high level of consistency even after many cycles. And they are generally much more reliable, too. In fact, ball valves are far more durable.
Gate valves can be prone to corrosion, whereas ball ones do not. This is because of the screw handle attached to the gate, which is constantly in contact with the material flowing through it. The screw handle can become corroded over time, reducing its performance.
The choice between gate and ball valves is usually based on cost and reliability. The key differences between the two are reflected in the cost of a ball valve and its size and function.

What Are Ball Valves?
Ball valves are simple structures with excellent sealing capabilities. They are lightweight, have small volumes, and are easy to install and operate. Because of their small size, they are easy to open and close within a nominal passage range. These advantages make them one of the fastest-growing valve varieties in the last decade.
Ball valves are typically made of two parts, the body, and the bonnet. The body is composed of the ball, with its seat and end connections secured by bolts. The stem is held inside the valve through the end caps, which are either socket welded or threaded; when you turn the handle, the stem moves and rotates the ball, which blocks the flow.
What Are Gate Valves?
Gate valves are a common part of many industrial processes, from food to pharmaceuticals. While the name suggests, there are many different types of gate valves. Gate valves are typically made from metal.
They’re sturdy and durable, so they can withstand high temperatures and pressures. Their function is to relieve pressure from pipes and regulate pressure. They have a solid body that houses all of the parts required for proper valve function. Their bodies are usually made from cast steel or forged steel.
Gate valves are commonly operated by an electric actuator. This type of valve has a disc that works like a gate. When you turn the handle, the gate blocks the flow, and when you open it, the gate moves up to allow the flow.
Are Ball Valves More Reliable Than Gate Valves?
If you are in the market for a new valve, you may be wondering: Are ball or gate valves more reliable? While they may seem similar, there are important differences. Ultimately, the best decision will depend on your specific application. Gate valves are commonly used in oil and gas production. Ball valves are more expensive than gate valves.
Air-operated ball valves are easy to operate. They rarely freeze and offer reliable service. Because they are so easy to operate, they are perfect for many different industries, including pharmaceuticals. Another great benefit of ball valves is their compact size and minimal installation space. You will save a lot of space by choosing a ball valve. Ultimately, this valve type will meet your needs for a long time.
The main difference between gate valves and ball valves is the way they shut off and open. Ball valves can be opened and closed quickly as you need to turn the handle only quarterly. On the other hand, in order to open and close the gate valve, you need to turn the handle 360 degrees.
Gate and ball valves both have advantages and disadvantages. Both valve types can be reliable in the same application. Ball valves, on the other hand, have higher reliability when compared to gate valves. Ball valves are generally easier to maintain, durable and simpler to use.
Ball valves are expensive, but they are highly durable compared to gate valves. Gate valves are better suited for smaller installation spaces, while ball valves are more durable and more reliable. Ball valves are durable and resistant to contaminated media, which makes them an excellent choice for shutoff applications. Furthermore, they are easier to use than gate valves, which makes them better for many applications.
