VEXVE balancing ball valve, DN250 PN25 flanged, reduced bore 143250/25

Balancing ball valve – precise regulation in heating and cooling systems

The VEXVE balancing ball valve, made of high-quality materials, is a reliable solution for precise flow control in central heating and air conditioning installations. Its design with a reduced bore ensures optimal performance and minimizes pressure loss, which translates to efficient operation of the entire system. The DN250 PN25 model with a flanged connection is particularly recommended for industrial applications and buildings with high hydraulic requirements.

Construction and application

This valve, with a nominal diameter of DN250 and a pressure class of PN25, is designed for flanged mounting, ensuring tightness and easy integration with existing infrastructure. The reduced bore minimizes flow resistance, and the control characteristic allows for accurate setting of the desired medium flow. A Kvs value of 3 indicates its intended use for medium flows in heating and cooling systems. Made of carbon steel P235GH (1.0345) or stainless steel X5CrNi18-10 (1.4301) – depending on the version – ensures durability and corrosion resistance.

Benefits of use

• Precise regulation: Allows for accurate adjustment of the medium flow, which translates to thermal comfort and energy savings.
• Durability and reliability: The use of high-quality materials guarantees a long service life even in harsh operating conditions.
• Easy installation: Flanged connection facilitates integration with the existing installation.
• Minimal pressure loss: The design with a reduced bore limits flow resistance, increasing system efficiency.
• Wide range of applications: Ideal for heating, cooling and industrial water systems.
• Temperature resistance: Suitable for operation in a temperature range from -30°C to +200°C (at temperatures below 0°C contact with the manufacturer is recommended).
• Leakage class A: Ensures minimal leakage in accordance with EN 12266-1, which translates to safety and energy efficiency of the installation.

The VEXVE type 143 valve is a proven component that will find application both in new installations and during the modernization of existing hydraulic systems. Its solid construction and precise regulation make it an ideal choice for professionals and demanding end-users.
