Static (or manual) balancing valves can adjust flow within a system, creating pressure drop.
They also enable flow measurement, either indirectly (measuring ΔP around an orifice) or directly (with Venturi valves).
There are two types of valve.
- Variable-orifice valves: 750, 750B and Vario
- Fixed-orifice valves: Venturi
