Expert Recommendation: The Best Choice of Valves for Sewage Piping Systems

Sewerage pipelines are an important part of urban infrastructure, and their main function is to collect and transport urban domestic and industrial wastewater. In a sewer piping system, choosing the right valve is critical to the proper operation of the system. This article will detail several commonly used sewer line valves and their characteristics to help you make the right choice.

Sewage system valve requirements: 

First of all, the sewage piping system is the construction of the building is the most commonly used and the most common water conservancy projects in life, the requirements of the valve according to the specific conditions have different requirements, in general, the use of the valve in the sewage piping system needs to have the following advantages:

Strong sealing:

Ensure that there is no leakage under high pressure and corrosive media to protect the environment and equipment.

Corrosion resistance:

 Able to withstand the chemicals in the sewage, prolonging the service life and reducing maintenance costs.

Easy operation:

Able to quickly open and close and adjust, convenient to use in different working conditions, reduce manual intervention.

Flow control:

With good flow regulation ability to meet the needs of different treatment stages.

.High degree of automation:

It can be linked with the monitoring system to facilitate remote control and intelligent management.

Strong adaptability:

Capable of adapting to different temperatures, pressures and piping layouts to flexibly respond to various operating conditions.

The combination of these valve advantages can ensure the efficient, safe and reliable operation of the sewage treatment system. Ensure the normal operation of sewage treatment.

Various characteristics of valves suitable for use in wastewater treatment systems：

Gate Valves

Features

Gate valve controls the passage of fluid through the lifting and lowering of the valve flap, and is suitable for occasions requiring full opening or full closing. It has a simple structure, good sealing performance, can withstand high pressure, and is particularly suitable for opening and closing operations in sewage pipelines

Application

Gate valves are suitable for applications that do not require frequent flow adjustment, such as sewage treatment inlet and outlet pipelines. Despite their slow opening and closing speeds, they perform well in stable flow control environments.

Globe Valves

Features

Globe valves have good flow control performance by rotating the valve stem to regulate the lifting and lowering of the valve flap. Its design makes the flow regulation more precise and is suitable for detailed flow regulation.

Application

Globe valves excel in wastewater treatment plants and where fine control is required. Despite its slow opening and closing speeds, its flow regulation capability is its greatest strength.

Ball Valves

Features

Ball valves control fluid flow by rotating a sphere, with fast opening and closing and good sealing performance. With compact structure and easy operation, it is especially suitable for quick opening and closing operation in sewage pipelines.

Application

Modern ball valves can choose corrosion-resistant materials to adapt to the corrosive nature of sewage, so in the sewage pipeline, ball valves are commonly used in occasions that require rapid switching, such as the import and export of sewage pumps.

Butterfly valve

Characteristics

Butterfly valve controls the fluid flow by rotating a disk-shaped valve flap, with the advantages of small size, light weight and rapid opening and closing.

Application

Butterfly valves are particularly effective when dealing with large-diameter sewage pipes. However, due to its relatively poor sealing performance, it needs to be carefully selected according to specific conditions when used, especially in high-pressure or highly polluted media.

Check Valve

Characteristics

Check valves are used to prevent backflow of fluids. When the fluid flows backwards, the valve will automatically close, thus protecting the piping system and equipment.

Application

Check valves are very important in sewage pumping stations and piping systems, which can effectively prevent sewage from flowing backwards and avoid damage to the system.

Exhaust Valve

Characteristics

The function of exhaust valve is to exclude the air or gas in the pipeline, prevent the phenomenon of air block or air plug, and ensure the smooth flow of sewage.

Application

In sewage piping systems, air venting valves help to maintain the stability of fluid flow and avoid flow problems caused by air accumulation.

Considerations for selecting valves

When selecting valves in the sewage piping system, the following factors should be considered:

Fluid properties:

Different sewage may have different chemical compositions, and suitable valve materials need to be selected to prevent corrosion.

Operational requirements:

According to the need for frequent opening and closing or stabilizing the flow requirements to select the appropriate type of valve.

Operating pressure:

Ensure that the selected valve can withstand the maximum operating pressure of the system.

Installation space:

Different valves have different structural dimensions, need to consider the limitations of the installation space.

Through reasonable selection and proper use of valves, you can improve the operational efficiency and safety of the sewage piping system and extend the service life of the equipment.

Conclusion

Choosing the right valve is crucial for the proper operation of the sewage piping system. We hope that through the introduction of this article, you can have a better understanding of the various types of valves and make an informed choice according to the actual needs.
