1. Regular Inspection

Inspect butterfly valves periodically to detect wear, corrosion, or leakage. JUHAN VALVE recommends checking disc, stem, and seat for signs of damage.

2. Lubrication

Ensure that moving parts such as stems and actuators are properly lubricated to reduce friction and wear. Pinless designs generally require less frequent maintenance.

3. Cleaning and Debris Removal

Keep the valve body and seat clean from deposits or debris that could impair sealing performance or obstruct operation.

4. Tightening and Alignment

Check flange connections, bolts, and actuator mounting regularly. Proper alignment ensures reliable operation and reduces stress on the valve components.

5. Testing and Performance Checks

• Cycle the valve to ensure smooth operation
• Verify leak-tightness under operating pressure
• Document inspection results for future reference
