R-30 SRM
2.3. Initial Start-up - The Control Valve
1.
Make sure that the upstream and the downstream isolation valves are closed [
12
] and [
12a
].
2. Slightly open the upstream isolation valve [ 12 ].
3. Check for leaks; tighten bolts & fittings, if necessary.
4. Turn the 3 -way selector [ 3 ] to its “AUTO” position.
5. Open the downstream isolation valve [ 12a ]; Make sure there is water demand downstream.
6.
Turn the adjusting screw of the PR pilot [
2a
] slowly clockwise, one turn at a time. Wait few seconds between turns,
allowing the valve to react until the downstream pressure reaches the required level; water starts to flow to the
pipeline.
7. Gradually continue to open the downstream isolation valve [ 12a ], until it is fully opened.
8.
Turn the adjusting screw of the SU pilot [
2b
] slowly clockwise, one turn at a time until the upstream pressure
reaches the required level.
Important note:
In case of high upstream pressure,
carefully monitor the downstream
pressure while opening the
downstream isolation valve; make sure
not to expose the pipeline to excessive
pressure.
