How to Identify the valve problem and repair the valve?

General guidelines once valve failure has occurred and been identified are as follows:

  1. Identify location of valve failure (seat, body, actuator, etc.).

  2. Take necessary troubleshooting steps to further identify root cause or to resolve while the valve is in place.

  3. Ensure appropriate spare parts are on hand before removing valve from service.

  4. Remove valve from piping (if necessary) following appropriate procedures, including air and electrical disconnection and lockout tagout.

  5. Follow proper disassembly and maintenance procedures to resolve issue and reassemble valve.

  6. Re-install valve into piping with correct air and electrical connections.

  7. Actuate and test valve to ensure proper function before production startup.

  8. Monitor valve during initial production run to ensure valve is operating correctly.
