Brass Balancing Valve with Flow Meter
Product Introduction
Specifications
Balancing Valve with Flow Meter, offers direct reading of flow rate, no sight gauge clouding or scaling.
The series balancing valve accurately sets the flow rate of heating and cooling transfer fluid supplied to fan coils and terminal units or where flow balancing is required in solar thermal systems. Proper hydronic system balancing ensures that the system operates according to design specifications, providing satisfactory thermal comfort with low energy consumption. The flow meter is housed in a bypass circuit on the valve body and can be shut off during normal operation. The flow meter permits fast and easy circuit balancing without added differential pressure gauges and reference charts. The balancing valve is furnished with a preformed insulation shell to optimize thermal performance or both hot and cold water systems.

Advantages of balanced circuits
Balanced circuits have the following principal benefits:
1. The system terminals operate correctly in heating, cooling and dehumidification without waste of energy and provide a better comfort.
2. The pumps run in their zone of highest efficiency, thus reducing the risk of overheating and excessive wear.
3. Too high medium speeds, which can result in noise and abrasion, are avoided.
4. The differential pressures acting on the regulation valves are limited in value, thus preventing faulty operation.
