  1. Measure the valve margin using an appropriate scale.
  2. Reference the specifications in this section for minimum valve margin and compare them to your measurements.
  3. If the valve margins are beyond specification, replace the valves.
  4. If the valve margins are within specification and do not require refacing, test the valve for seat concentricity using the Valve-to-Seat Concentricity Measurement Procedure.
