Gate valve and ball valve are two different valves, and there are differences in use, so you can't simply say who is good and who is bad, list the advantages and disadvantages of gate valve and ball valve for your reference:

Advantages of Gate Valve:

1. The flow resistance is small, the medium channel inside the valve body is straight, the medium flows in a straight line, and the flow resistance is small.

2. It is more labor-saving when opening and closing, which is compared with the globe valve, because whether it is open or closed, the direction of movement of the ram is perpendicular to the direction of medium flow.

3. The height is large, the opening and closing time is long, the opening and closing stroke of the ram is large, and the lifting is carried out through the screw.

4. The phenomenon of water hammer is not easy to occur, because of the long closing time.

5. The medium can flow in any direction on both sides, which is easy to install, and the two sides of the gate valve channel are symmetrical.

Disadvantages of gate valves: erosion and abrasion are easy to cause between sealing surfaces, and maintenance is difficult. The overall size is large, and a certain amount of space is required for opening, and the opening and closing time is long. The structure is more complex.

Advantages of Ball Valves:

1. It has the lowest flow resistance (actually 0);

2. Because it will not get stuck when working (when there is no lubricant), it can be reliably used in corrosive media and low boiling point liquids;

3. In a large range of pressure and temperature, it can achieve complete sealing;

4. It can realize rapid opening and closing, and the opening and closing time of some structures is only to ensure that it can be used in the automation system of the test bench. When the valve is opened and closed quickly, there is no impact in operation;

5. The spherical closing part can be automatically positioned at the boundary position;

6. The working medium is sealed and reliable on both sides;

7. When fully open and fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, so the medium passing through the valve at high speed will not cause the erosion of the sealing surface;

8. The ball valve with the all-welded valve body can be buried directly in the ground, so that the valve trim is not corroded, and the maximum service life can reach 30 years, which is the most ideal valve for oil and gas pipelines.

Disadvantages of ball valves: PTFE, the seat seal ring material, has a low temperature resistance rating and can only be used in the case of less than 180C. Beyond this temperature, the sealing material will deteriorate. In the case of long-term use, it will generally only be used under 120.

The advantages of gate valves are low resistance, tight closing, no water hammer, and are widely used in shut-off valves for various liquids and gases.

It also has a certain adjustment function, but when it is partially opened, the ram is susceptible to fluid wetting, and the alarm plate flutters when the fluid flows, and the sealing surface is easy to wear.

The disadvantage of the gate valve is that the structure is complex, it is more expensive, it is not easy to repair, and the solid substance is easy to be deposited in the valve seat groove and is not tightly closed.

The ball valve has a simple structure, the ball valve is light in weight compared with the globe valve, the structure is relatively simple, and its overall weight is very light, so it can play a good role in the low-temperature medium system.

The ball valve seal surface is easy to process, the sealing is good, the operation is easy, the opening and closing is fast, and the start-up and closing time is very short, which enables the testing system to be quickly optimized, and there is no shock during the start-up and closing of the valve.

Ball valves cannot be used to regulate flow and are suitable for high-pressure pipelines.

The advantages of some gate valves are low resistance, tight closing, no water hammer, and are widely used in shut-off valves for various liquids and gases. It also has a certain adjustment function, but when partially opened, the ram is susceptible to fluid wetting, and the ball valve cannot be used to regulate the flow rate, which is suitable for high-pressure pipelines.

Hope it helps.

According to years of practice, it is concluded that the gate valve is better than the goal in terms of flow adjustment. However, the switch is slower. The ball valve is fast to open and close, but the frequent opening and closing produces internal leakage, and the durability is not as good as that of the gate valve.

The ball valves are better Kanghao, Yatai, Feiqiu, Kars, and Houpu.
