Balancing valve DN150, FIG.447 447A150C72

Balancing Valve – Precise Flow Control in Installations

The balancing valve Fig. 447 is a reliable device designed for regulating and limiting flow in heating, cooling, and water supply systems. Constructed from cast iron with flanged connections, it ensures durability and corrosion resistance. Designed for operation in systems with temperatures ranging from -10°C to 120°C and a nominal pressure of PN16, its design enables precise flow setting, resulting in optimal system performance and enhanced user comfort.

This valve is suitable for both new installations and modernization of existing systems. Thanks to high tightness (Class A per EN 12266-1), it minimizes leakage risks and energy losses. Its compatibility with other valves and compact design simplify installation and integration with diverse hydraulic systems.

Construction and Key Features

The balancing valve Fig. 447 features a robust construction based on a cast iron body (material grade GG25). It is equipped with a manual handwheel for flow adjustment. The valve flanges are machined in accordance with EN 1092-2 and ANSI B16.1 Class 125 standards, ensuring compatibility with a wide range of pipes and fittings. The Kvs value for DN150 is 390.2, indicating high flow capacity. Additionally, the valve includes measurement ports for monitoring flow parameters.

The use of GG25 cast iron guarantees mechanical strength and corrosion resistance, ensuring long service life even under demanding operating conditions. The compact design facilitates installation in confined spaces, while compatibility with other system components enhances its versatility.
