💡Valve Maintenance Insights💡

For users, ensuring the actual operating conditions match the valve’s specified scope, along with proper operation and maintenance, is key to preventing failures and extending service life.

Check out common valve failure, causes, and solutions:

🔧Failure: Leaking outward at the packing

📌Cause analysis:

1.The packing is in exceeded use and gets aged.

2.Excessive force is used in operation.

3.The eyelet bolt is not tightened.

🛠️Method of settlement:

1.Replace the aged and injured packing in time, place the connectors turn by turn and let them 30° - 50°.

2.Use normal even operation and do not use bushing or any other ways.

3.Evenly tighten the bolts used to tightly press the packing.
