R-30 S
2. Make sure that there is a downstream flow demand
.
3. Make sure that the upstream pressure is higher or equal to the required pressure.
4. Turn the pilot valve’s locking nut ( 4 A) counter clockwise, until it touches the adjusting bolt ( 4 B) head.
5. Make sure all 2 -way ball valves ( 3 ) are open.
6. Turn adjusting bolt ( 4 B) counter-clockwise until the valve starts to open.
7.
To increase upstream pressure, turn the adjusting bolt (
4
B) clockwise, one turn at a time, allowing sometime
between turns for the valve to respond. Downstream pressure is shown on the pressure gauge (
5
). Continue until
required pressure is reached.
8.
To decrease upstream pressure, turn the adjusting bolt (
4
B) counterclockwise, one turn at a time, allowing
sometime between turns for the valve to respond. Downstream pressure is shown on the pressure gauge (
5
).
Continue until required pressure is reached.
9.
When required pressure is reached, prevent the adjusting bolt (
4
B) from turning, and turn the locking nut (
4
A)
clockwise until it touches the pilot bonnet. Tighten the nut carefully.
3. OPERATION INSTRUCTIONS
1. To manually open the valve, close the 2 -way inlet ball valve ( 3 ). Make sure that the 2 -way outlet ball valve ( 3 a) is
open.
Please note:

By doing so you will have no control over the system pressure and flow-rates.

The valve cannot fully open when the control loop is of a two-way type.
2. To manually close the valve, close the 2 -way outlet ball valve ( 3 A). Verify that 2 -way inlet ball valve ( 3 ) is open.
3. To maintain downstream preset pressure, open inlet and outlet ball valves ( 3 ), ( 3 A).
