VEXVE ball valve for hot tapping, DN150 PN25 for welding, reduced bore 126150

Ball valves for hot tapping – reliability and durability in heating systems

The VEXVE ball valve, designed for hot tapping, is a key element of heating and cooling installations. Made of steel, it is characterized by high corrosion resistance and mechanical damage resistance, which guarantees long-term and trouble-free operation. The DN150 PN25 model, designed for welding, offers an effective and tight connection in the pipeline. Reduced bore minimizes flow resistance, affecting the optimization of system efficiency.

Design and practical application

VEXVE valves from the X series are distinguished by an all-welded construction made of high-quality steel for pressure vessels. This solution ensures strength and reliability in various operating conditions – even with changes in water quality. The lightweight and compact design facilitates installation and thermal insulation. This valve finds wide application in district heating, cooling networks and HVAC systems. The possibility of welding ensures a durable and tight connection with the pipeline, minimizing the risk of leaks.

Key features ensuring efficiency and safety

• Tightness: Two-way tightness (class A according to EN 12266-1) guarantees no loss of medium and safe use.
• Durability: Construction with a floating ball and ball seals with a spring mechanism ensures resistance to axial loads resulting from thermal expansion and pressure surges.
• Safe operation: Stem design resistant to blow-out ensures safe valve operation and precise flow control. A 90-degree position limiter makes it easier to control the valve status.
• Easy installation: Lightweight construction and easy thermal insulation significantly simplify the installation process.
• DBB function (Double Block and Bleed): Allows the valve body to be drained of water to check its tightness without having to shut down the entire system – particularly useful during inspections and maintenance.
• Automatic pressure relief (SPE): The SPE system reduces the pressure between the ball and the valve body, preventing problems related to temperature changes.
