Installation and Operation
Installation:
- Ensure the pipeline is clean and free from debris before installation.
- Position the valve between the pipeline flanges and align the bolt holes.
- Insert and tighten the bolts evenly to secure the valve in place.
- Connect the pneumatic actuator to the air supply and control system as per the wiring diagram provided.
Operation:
- The valve can be operated remotely via the control system.
- For manual operation in case of actuator failure, use the manual override feature on the actuator.
- Regularly check the valve and actuator for any signs of wear or damage.
Maintenance:
- Periodically inspect the sealing surfaces and replace seals if necessary.
- Lubricate the moving parts of the actuator as per the manufacturer's recommendations.
- Ensure the pneumatic connections are secure and free from leaks.
Safety Precautions
- Always depressurize the pipeline before performing any maintenance.
- Disconnect the air supply to the actuator before servicing.
- Use appropriate personal protective equipment (PPE) when handling the valve and during maintenance.
Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Valve does not open/close | Air supply failure | Check and restore air supply |
| Leakage | Worn or damaged seals | Replace seals |
| Actuator malfunction | Pneumatic fault or leakage | Inspect and repair or replace actuator |
| No response to control signal | Faulty wiring or control system | Verify wiring and control system integrity |
