Applications of a DZR Balancing Valve
A DZR balancing valve is used in water-based heating and cooling systems where monitoring and balancing flow rates is important. During commissioning, engineers can use the valve’s test points with a suitable differential pressure measuring instrument to assess water flow through the system.
Correct flow measurement can help engineers identify whether a system is operating within its intended design parameters. This makes fixed orifice balancing valves useful in suitable commercial heating, cooling and building services installations.
Selecting the Correct Balancing Valve
The VIP DZR Fixed Orifice Balancing Valve is available in multiple connection sizes, with specified flow ranges for different applications. Before ordering, check the required connection size, expected flow rate, operating temperature and system pressure to ensure the selected valve is suitable.
The valve has a nominal Kvs tolerance of ±3%, tested in accordance with BS 7350. Water operating temperatures range from -10°C to 130°C, subject to the manufacturer’s stated conditions. Below 0°C, water must contain suitable antifreeze fluid; above 100°C, suitable anti-boiling fluid is required.
