2.
Make sure that there is a downstream flow demand
.
3.
Turn the pilot valve’s locking nut (
4
A) counter clockwise, until it touches the adjusting bolt (
4
B) head.
4.
Make sure that the
2
-way ball valves (
3
) are open.
5.
Turn the adjusting bolt (
4
B) clockwise until the valve starts to open.
6.
To increase the downstream 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 the required pressure is reached.
7.
To decrease the downstream 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 the required pressure is reached.
8.
When the 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 downstream pressure; it is possible that your
system will be exposed to excess pressure.
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 the
2
-way inlet ball valve (
3
) is open.
3.
To maintain downstream preset pressure, open the inlet and the outlet ball valves (
3
), (
3
A).
