Product Introduction: Fully Welded Ball Valve

The fully welded ball valve is a high-performance industrial valve designed for urban heating and urban gas pipelines. It adopts a fully welded structure, ensuring superior sealing performance, durability and low maintenance requirements. The design of the valve optimizes the welded connection to ensure leak-free operation under medium and low pressure and temperature conditions, especially suitable for urban heating and gas systems.


 Product Structure and Features

 Fully Welded Structure

– Durable and leak-free connection:

The fully welded connection provides a strong, seamless connection between the valve and the pipeline, eliminating potential leak points and ensuring a long-term safe and reliable connection.

– Suitable for medium and low pressure applications:

The welded connection is able to withstand higher pressures, but in urban heating and gas pipelines, the pressure is usually not very high, so it is very suitable for such applications.

– Enhanced corrosion resistance:

The welded structure eliminates gaskets and bolts, reducing the risk of corrosion, thereby extending the service life of the valve.

– Improved flow characteristics:

The smooth flow path reduces turbulence and pressure loss, improving the efficiency of the valve.


 Modular design

– Easy to install and maintain:

The fully welded design simplifies the installation and maintenance process of the valve, and is particularly suitable for the installation requirements of urban pipeline systems.

– High reliability:

After precise design and manufacturing, the fully welded ball valve provides excellent sealing performance and long-term reliability.


 Medium and working conditions

Fully welded ball valve is suitable for a variety of media and working conditions:

 Medium

– City heating:

Suitable for hot water and steam pipeline systems to ensure efficient and safe heat transfer.

– City gas:

Suitable for the transmission and control of natural gas or city gas, providing reliable gas flow regulation.


 Working conditions

– Temperature range:

The standard design is suitable for a temperature range of -20°C to 150°C, which is suitable for common temperature conditions of urban heating and gas pipelines.

– Pressure range:

Suitable for medium and low pressure applications, usually with pressure below 25bar/150LB, meeting the needs of urban pipelines.

– Environmental adaptability:

Suitable for indoor and outdoor installation, including various environmental conditions of urban heating and gas systems.

 Advantages

– Strong durability:

The valve structure with high-strength welding ensures long-term use under harsh working conditions.

– Low maintenance requirements:

The fully welded design reduces maintenance frequency and reduces operating costs.

– Safe and reliable:

The leak-free design improves the safety of the system and reduces the risk of leakage and potential dangers.

– Widely applicable:

Applicable to urban heating and gas pipelines, providing flexible fluid control solutions.


 Summary

Fully welded ball valve is an ideal choice for the fluid control needs of urban heating and urban gas pipelines. Its welded structure provides a safe, leak-free connection and can operate stably under medium and low pressure and temperature conditions. With its modular design, easy maintenance and adaptability to various media and conditions, this valve is an ideal product for those who pursue high quality and reliability. Whether it is used for hot water and steam transmission or natural gas transmission, the fully welded ball valve has demonstrated superior performance and reliability and is a trustworthy choice.
