 Product Structure and Features

 3-Piece Design

– Modular Structure:

The three-piece design allows for easy access to internal components (such as the ball and seal seat) by removing the connection bolts. This eliminates the need to remove the valve from the pipeline, simplifying maintenance and reducing downtime.

– Installation Flexibility:

The modular design offers flexibility in installation and alignment, ensuring proper fit and function in complex piping systems.

 Butt-Weld Structure

– Permanent and Leak-Free Connection:

The butt-weld connection provides a strong, seamless link between the valve and the pipeline. This eliminates potential leak paths, ensuring a secure, long-term connection.

– Suitable for High-Pressure Applications:

Welded connections can withstand higher pressures and are more suitable for high-pressure applications compared to flanged connections.

– Enhanced Corrosion Resistance:

Welding removes the need for gaskets and bolts, reducing corrosion risks and extending the valve’s lifespan.

– Improved Flow Characteristics:

The smooth, uninterrupted flow path reduces turbulence and pressure loss, enhancing valve efficiency.


 Media and Working Conditions

The 3-Piece Butt-Weld Ball Valve is designed to handle various media and harsh working conditions:

 Media

– Liquids:

Suitable for water, oil, and other non-corrosive liquids.

– Gases:

Appropriate for natural gas, steam, and other gaseous media.

– Corrosive Liquids:

Designed for corrosive substances like acids and alkalis, depending on the valve materials used.


 Working Conditions

– Temperature Range:

Typically operates within a temperature range of -40°C to 300°C, depending on the materials used.

– Pressure Range:
