Balancing valve DN300, FIG.447 447A300C72

The balancing valve DN300, Fig. 447, is a component designed for precise flow regulation in systems, ensuring optimal hydraulic balance. Manufactured from GG25 cast iron, it offers high durability and corrosion resistance. Designed to work in conjunction with other valves, it enables the creation of comprehensive regulatory systems.

This valve is suitable for use in central heating, air conditioning, cooling, water supply, and industrial installations. Its oblique-body design with flanged connections ensures low flow resistance and minimizes pressure losses. Thanks to its high sealing class (A according to EN 12266-1), it guarantees safe and reliable operation.

Design and Functional Features

The balancing valve Fig. 447 features a manual handwheel for flow adjustment. A Kvs value of 1504.1 indicates high flow capacity, making it an ideal solution for systems with demanding hydraulic requirements. Flanges are machined in accordance with EN 1092-2 and ANSI B16.1 Class 125 standards, ensuring compatibility with various pipe systems. Installation length complies with EN 558 Series 1, facilitating integration into existing installations.

This valve enables not only flow regulation but also initial setting, flow measurement, and media shut-off. Integrated measurement ports allow precise monitoring of system operating parameters. Note: This valve is not compatible with actuators and does not feature a drain function.

Materials and Compliance with Standards

The valve body is manufactured from GG25 cast iron (GJL-250), providing high mechanical strength and corrosion resistance. The seal is made of EPDM, ensuring tightness and long-term durability of connections. The valve meets the requirements of EN 12266-1 for sealing performance and has undergone testing and certification to confirm its quality and safety. It operates within a temperature range of -10°C to +120°C at a nominal pressure of PN16.

The balancing valve Fig. 447 is a robust and reliable solution for professionals and end-users seeking an efficient method for flow regulation in hydraulic systems. Its versatility and compliance with current standards make it an ideal choice for diverse industrial and construction applications.
