What types of final control elements should we choose for manipulating the following products:

1. steam at 25 bar;

2. flow of acetic acid at 10 l/h nominal flow;

3. air flow at 100 Nm³/h and pressure 0.5 bar;

4. sulfuric acid 60 % produced through the contact chamber process;

5. water emulsion of polyvinyl acetate flow;

6. air conditioning air flow at 300 mmH₂O pressure;

7. slurry flow at the bottom of a distillation column;

8. sand flow for the glass production process.
