What are the 4 types of ball valves?

Ball valve is a very common type of valve, widely used in various industrial and civilian fields. According to their structural and functional characteristics, ball valves can be divided into the following four main types:

Floating Ball Valve

Features:

Under the pressure of the medium, the sphere can produce a certain displacement, thereby achieving sealing.

Usually used in medium and low pressure pipeline systems.

Simple structure and low cost.

Application Scenario:

Applicable to pipeline systems for media such as water, steam, and oil.

Suitable for occasions where sealing requirements are not particularly high.

Trunnion Ball Valve

Features:

The sphere is fixed in the valve body and does not move with the pressure of the medium.

Usually used in high-pressure and large-diameter pipeline systems.

The structure is complex and the cost is high, but the sealing performance is better.

Application Scenario:

High pressure pipeline systems suitable for industries such as petroleum, natural gas, and chemical.

Suitable for occasions that require high sealing and reliability.

V-Port Ball Valve

Features:

The valve core has a V-shaped notch, which can achieve precise flow control.

Usually used in situations where flow regulation is required.

Compact structure and good adjustment performance.

Application Scenario:

Suitable for systems that require precise flow control, such as chemical, pharmaceutical, food processing, and other industries.

Suitable for occasions that require frequent adjustment.

Three Way Ball Valve

Features:

The valve body has three channels that can achieve the diversion or mixing of media.

Usually used in situations where the flow direction of the medium needs to be changed.

Compact structure and easy operation.

Application Scenario:

Suitable for systems that require diversion or mixing of media, such as chemical, petroleum, natural gas, and other industries.

Suitable for situations where flexible control of medium flow is required.

Other types

In addition to the four main types mentioned above, there are also some special types of ball valves, such as:

Insulated ball valve: used for media that require insulation, such as liquefied gas.

Fluorine lined ball valve: used for corrosive media such as acids, alkalis, etc.

Sanitary ball valve: used in industries with high hygiene requirements such as food and pharmaceuticals.

Each type of ball valve has its unique structure and application scenarios, and the selection needs to be determined based on specific working conditions and requirements.
