The difference between the application scenarios of ball valves and gate valves

The application scenarios of ball valves and gate valves are as follows:

Ball valve

Ball valve is a rotary valve, its sphere has pressure resistance and corrosion resistance. Widely used in petroleum, chemical, water treatment, natural gas and other industries. Specifically, ball valves are suitable for the following scenarios:

• High-pressure scenarios: Ball valves can withstand high pressure and are widely used in high-pressure media control scenarios.
• High temperature scenario: Because the internal medium of the ball valve does not contact the sealing surface. Can cope with high temperature media control.
• High viscosity scenario: The ball structure of the ball valve is simple, without complex structures such as spool and seat. Suitable for high viscosity media control.
• Easy crystallization scenario: Due to the simple structure of the ball valve, the medium can be prevented from crystallizing in the ball. Suitable for control scenarios of easily crystallized media.

Gate valve:

A gate valve is a valve that controls the flow of the pipeline by moving the gate plate up and down. Widely used in petroleum, chemical, electric power, metallurgy and other industries. Gate valves are suitable for the following scenarios:

• Low viscosity scenario: The internal disc and seat of the gate valve are equipped with a sealing surface, which can well control the low viscosity medium.
• Low pressure scenario: the sealing surface of the gate valve has a large contact area. Which is suitable for low pressure media control.
• Flow regulation scenario: Since the gate valve can adjust the flow rate by lifting the gate plate, it is suitable for flow regulation scenarios.
• Scenarios with high sealing requirements: Gate valves have good sealing performance and can cope with demanding medium control scenarios.

In summary, although ball valves and gate valves are valves, they are different in the use scenario. Selecting the right valve type according to different media and control requirements can ensure the safe and stable operation of the pipeline system.
