Balancing valve DN80 FIG.447 447A080C72

Balancing valve for precise flow regulation

This Zetkama Fig. 447 DN80 cast iron balancing valve is a reliable solution for precise flow regulation in heating, cooling and industrial installations. Its construction, based on proven materials and technologies, guarantees long-lasting and trouble-free operation. The valve is designed for mounting on flanged connections, which facilitates integration with existing infrastructure.

This valve is used both in new installations and in the modernization of existing systems. Thanks to the possibility of manual adjustment, it allows for accurate balancing of hydraulic circuits, which translates into optimal energy use and comfort. This is particularly important in systems with different heat or cooling loads, where it is necessary to ensure uniform distribution of the medium.

Design and parameters for professionals

The valve is made of high-quality cast iron GG 25 (GJL-250), which ensures strength and corrosion resistance. The flanges are drilled according to EN 1092-2 and ASME B16.1 class 125 standards, which guarantees compatibility with various types of connections. The flow coefficient Kvs at 113.4 allows for effective flow regulation in high-performance installations. The regulating mechanism based on a handwheel provides precision and ease of operation.

The valve is characterized by a high degree of tightness class A according to EN 12266-1, minimizing the risk of leaks and energy losses. The compact design facilitates installation even in tight spaces. Tests and studies conducted in accordance with EN 12266-1 confirm its reliability and safety of use. Measurement ports allow for monitoring of flow parameters, which is useful during commissioning and servicing of installations.
