Common Faults and Solutions for Marine Angle Valves

Fault Symptom: Valve stem leakage

Possible Causes:

1. Packing wear (usage time > 8000 hours)

2. Scratches on the valve stem surface

3. Loose gland bolts

Solutions:

1. Online packing replacement procedure:

- Keep the valve in the fully open position

- Loosen the gland bolts and remove the old packing

- Add new PTFE packing one turn at a time (JIS R3431 standard)

- Tighten the gland bolts symmetricall
