|  | CAUTION
Single person operation Human body parts must be kept out of the valve opening and away from moving parts.

Description
Preconditions of Gate Adjustment: | Bonnet must be disassembled.
1. Close valve and check if pendulum plate is in center of flange. Check can be done either visual or by measurement. | When the valve is mounted to a tool, the bonnet has to be removed and the center position can be measured by a depth gauge (see 6.) If the centering (expected distance) is not correct, proceed:
2. Run CPA. | Available on CPA Version 4.2.1.
3. Set access mode to Local. |
4. Open Gate Adjustment Valve will switch to Maintenance Speed. |
5. Start Initialization by pressing «Start». The valve will do a homing and close, if necessary. |
| Valve is doing a movement after pressing «OK». Human body parts must be kept out of the valve opening and away from moving parts.
6. Measure value of distance [mm]. Measured distance between bonnet flange surface and pendulum plate. Maximum of adjustable value is ±1.5mm. |
DN | 63-100 | 160 | 200 | 250 | 320 | 350
Expected distance [mm] | 51.5 ± 0.5 | 45.0 ± 0.5 | 40.0 ± 0.5 | 50.0 ± 0.5 | 60.0 ± 0.5 | 61.0 ± 0.5
7. Type in measured distance if value ≥ ±0.5mm of expected distance. If value is in expected distance range the gate is adjusted. |
8. Press «Adjust», the valve will correct the center position of the gate. |
| Vale is doing a movement after pressing «OK». Human body parts must be kept out of the valve opening and away from moving parts.
9. Re-measure the distance. Distance should be in distance range, otherwise retry the whole procedure. |
10. Close Gate Adjustment by closing the window. The maintenance speed will reset to normal speed. Make sure that the access mode is set to «Local», closing the Gate Adjustment tool will also ensure that the maintenance speed mode changes back to normal speed. If the access mode is set to «Remote», the valve will remain in maintenance speed mode after closing the Gate Adjustment tool. To switch to normal speed, restart the valve. |
