Balancing ball valve VEXVE, DN150 PN16 flanged, reduced bore 143150

Vexve ball valves – reliability and durability in heating and cooling systems

Vexve DN150 PN16 balancing ball valve with flanged connection and reduced bore is an element designed for use in district heating, cooling networks and HVAC systems. The design of this valve combines solid construction, ease of installation and high functionality, making it an ideal solution for both professional installers and end users.

Design and application

Vexve ball valves are characterized by an all-welded construction made of high-quality materials, including steel for pressure vessels. This makes them resistant to various media and ensures long-term, trouble-free operation. The reduced bore in this model allows for effective flow control while minimizing pressure loss. This valve is used in heating, cooling systems, as well as in compressed air or oil networks. The ball design supported at the bottom (characteristic of sizes ≥ DN 600) provides additional support and stability, particularly important for larger diameters.

Advantages and benefits

• Durability and tightness: The all-welded construction eliminates the risk of leaks and ensures a long service life of the valve. Meets the requirements of EN 12266-1 standard, tightness class A – a guarantee of complete two-way tightness.
• Easy installation and insulation: Lightweight and compact design facilitates installation, and the possibility of full insulation minimizes heat loss. Four lifting lugs make it easy to handle the valve even in tight spaces.
• Safe operation: Stem design resistant to blow-out ensures safe valve operation. 90-degree position limiter allows for precise flow control.
• 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.
• Automatic pressure relief (SPE): The ball sealing system has a function of automatic pressure relief from inside the body, which prevents its increase caused by temperature changes.
• High Kv value: Minimizes pressure loss, reducing pumping costs.
• Versatility: Possibility of mounting in any position and a wide range of available connections (welded according to EN/DIN/GOST standards, flanged or threaded) increase the flexibility of valve application.
