Engineering Notes:
- Series 13 Limitation: Not recommended for >120°C service or DN≥500 valves
- Galvanic Protection: Use dielectric kits when connecting to carbon steel piping
- Disc Maintenance: Field-polish with 400-grit max to preserve corrosion resistance
- Seat Replacement: Requires valve removal – Series 14 allows in-line servicing
