Fully Welded Ball Valves

Product Overview

The All-Welded Ball Valve is an industrial valve designed to provide safe, durable sealing and flow control in low and medium pressure systems. It is made from unique welded steel plates such as Q235, Q345 and 16Mn for superior strength, durability and resistance to mechanical stress. The valve is commonly used in applications such as district heating systems, municipal water supplies and urban infrastructure projects.

The valve features an all-welded body to ensure a flangeless or threaded connection, eliminating potential leak points and providing a more robust, leak-proof solution for critical applications. It is suitable for low pressure systems (typically up to PN25) and can operate efficiently in temperatures up to 150°C, making it ideal for industries requiring safe and reliable flow control.

Product Features

All-welded structure: Valve body structure: The valve is made of high quality welded steel plate such as Q235, Q345 and 16Mn, which makes the structure strong and leak-proof. The welded design eliminates the need for flanged or threaded connections, providing higher strength and a seamless design.

Welding process: Fully welded construction ensures no potential leak points, ideal for highly reliable and long-life systems such as district heating and water supply.

Material selection: The valve body is made of Q235, Q345 and 16Mn, which are widely recognized for their strength and corrosion resistance. These materials ensure that the valve maintains good performance under various operating conditions, with excellent mechanical properties and reliability.

PTFE Seals: PTFE (polytetrafluoroethylene) seals are used to ensure a tight seal with high chemical resistance and low friction, ensuring long-term reliability and leak-proof performance in most industrial and municipal systems.

LOW-MEDIUM PRESSURE COMPATIBILITY: Designed for low to medium pressure applications up to an effective working pressure of PN25 (150 LB), this valve is the preferred choice for municipal heating lines, water supply networks and HVAC systems.

Temperature range: The valves can withstand temperatures up to 150°C and are suitable for low-temperature systems such as district heating and water treatment systems.

Compact, space-saving design: The all-welded construction is compact and space-saving for installation, making it ideal for space-constrained projects such as underground piping or compact water systems.

Low Maintenance: The valve's welded design and PTFE seals help minimize maintenance requirements, reduce downtime and extend valve life.

Product Advantages

Leak-proof performance: Fully welded construction ensures a leak-proof design, eliminating the risk of leakage at connection points, which is essential to ensure the integrity of critical systems such as heating and water supply.

High durability: The valve body is made of high-strength steel plates such as Q235, Q345 and 16Mn, which can withstand mechanical stress and wear and tear, ensuring a long service life even under harsh working conditions.

Cost-effective solution: The welded design eliminates the need for flanged or threaded connections, reducing installation complexity and cost while minimizing the risk of leakage.

Reduced risk of failure: The all-welded design provides better protection against system failures, especially in critical infrastructure projects where reliability is essential, such as district heating.

Wide range of applications: Suitable for use in district heating systems, municipal water supplies and HVAC systems, the valve handles water and low-temperature heating fluids and is versatile in a variety of applications.
