Butterfly Valve Maintenance Guide for Maximum Service Life

Proper maintenance extends butterfly valve life and prevents costly downtime. Follow this professional guide from Wofer Valve:

  1. Regular Inspection Check for leakage, corrosion, and actuator function every 3-6 months.

  2. Lubrication Apply silicone-based lubricant to stem and seals annually.

  3. Cleaning Remove debris from disc and seat. Avoid harsh chemicals on soft seals (EPDM, PTFE).

  4. Torque Check Ensure actuator torque settings match specifications.

  5. Storage Store in dry, slightly open position to prevent seat deformation.

  6. Common Issues & Solutions

    • Leakage: replace seals

    • Sticking: clean and lubricate stem

    • Disc damage: replace disc
