Balancing valve DN20 FIG.221 221H020D60

Balancing valve for precise flow control

The balancing valve DN20, type FIG.221, is a reliable solution for flow regulation in heating and cooling systems. Made of high-quality brass (CuZn36Pb2As – CW602N), it ensures durability and corrosion resistance. Its design with threaded connections (G1/2") facilitates installation and integration with existing systems. This valve is particularly useful where accurate hydraulic balancing of circuits is required, which translates to optimal system performance and reduced operating costs.

Construction and application

The ZETKAMA 221H020D60 balancing valve is designed for use in industrial water installations – both cold and hot – and in systems with glycol (up to 45% glycol content). Equipped with an opening indicator, it allows for precise setting of the desired flow. The throttling mushroom made of CuZn36Pb2As and the PTFE seal guarantee a high degree of tightness (class A according to EN 12266-1). This minimizes pressure losses and ensures stable operation of the installation.

This valve finds application in:

• central heating installations,
• air conditioning and cooling systems,
• industrial water installations,
• glycol systems.

Key features and benefits

• Precise regulation: Allows for accurate hydraulic balancing of heating and cooling circuits, which translates to even heat or cold distribution.
• High tightness: Class A according to EN 12266-1 ensures minimal pressure losses and eliminates the risk of leaks.
• Durability: Made of brass (CuZn36Pb2As) guarantees corrosion resistance and long life.
• Easy installation: Threaded connections facilitate integration with existing installations.
• Versatility: Designed to work with water, glycol and other inert media.
• Ergonomic operation: Handwheel with setting scale provides convenient use and precise adjustments.
• Adjustment locking possible: Prevents accidental adjustment of the valve after adjustment.

The ZETKAMA balancing valve is an investment in energy efficiency and comfort of use of the heating or cooling system. Its solid construction and precise operation make it the ideal choice for both professional installers and demanding end users.
