Setting STAD
Setting of a valve for a particular pressure drop, e g corresponding to 2.3 turns on the graph, is carried out as follows:
1. Close the valve fully (Fig 1).
2. Open the valve 2.3 turns (Fig. 2).
3. Using a 3 mm Allen key, turn the inner spindle clockwise until stop.
4. The valve is now set.
Fig. 1. Valve closed
Fig. 2. The valve is set at 2.3
Fig. 3. Fully open valve
To check the setting:
Close the valve, the indicator shows 0.0.
Open it to the stop position.
The indicator then shows the set value, in this case 2.3 (Fig. 2).
