Balancing valve DN65, FIG.447 447A065C72

Balancing valve for precise flow control

This cast iron balancing valve, with a nominal diameter of DN65 and designation Fig. 447, is a key component in heating and cooling systems. It is used to precisely regulate the flow of medium, ensuring optimal operating conditions and user comfort. It is a reliable solution for both professional installers and end-users who value efficiency and durability.

The valve is characterized by a high degree of tightness (class A according to EN 12266-1), which minimizes the risk of leaks and energy losses. The GG 25 (GJL-250) cast iron construction guarantees strength and corrosion resistance, and the handwheel enables intuitive and accurate adjustment. This makes the valve perfect for demanding operating conditions.

Construction and practical application

The balancing valve from the 447 series is designed for mounting on DN65 flanged connections. Its construction allows it to work with other valves to create complex control systems. The Kvs value of 88.8 indicates its performance and ability to pass significant amounts of medium. Measurement ports allow easy reading of flow parameters, which facilitates diagnostics and optimization of installation operation.

This valve finds application in:

• Central heating systems
• Air conditioning and cooling systems
• Industrial installations
• Heat and water distribution systems

Thanks to the possibility of cooperation with actuators (although not standard in this version), the valve can be integrated with automatic control systems, increasing comfort and energy efficiency. The use of materials such as cast iron and structural composite plastic ensures long-term reliability even in difficult working conditions. The flanges are drilled according to EN 1092-2 and ANSI ASME B16.1 class 125 standards, ensuring compatibility with various types of installations.
