4. Select suitable Combi valve VPF43.../1
5. Determine dial setting using volumetric flow/dial presetting tables, see below.
Example
1. Heat demand Q = 150 kW
2. Temperature spread ∆T = 6 K
3. Volumetric flow

Hint: You can also determine the volumetric flow using the valve slide rule.
4. Select Combi valve VPF43../1
Ideally, Combi valves should be selected such that they operate at about 80%
of their maximum flow, enabling them to deliver spare capacity, if required.
