How to maintain the breathing valve of waste oil tank

Conduct routine visual inspections of the breathing valve. Check for signs of corrosion, dirt, or debris accumulation on the valve body, cover, and internal components. Inspect the gaskets and seals for signs of wear or damage.

Periodically clean the breathing valve to remove contaminants. Use a soft brush or non-abrasive cloth to gently clean the surfaces. For stubborn deposits, use a mild solvent compatible with valve materials.

After cleaning, thoroughly rinse with clean water and allow complete drying before reinstalling to prevent moisture-related corrosion.

Regularly test the valve's functionality. Verify it can open and close smoothly under normal pressure changes using a pressure testing device.

Check that the valve opens at specified positive and negative pressure settings to release excess pressure or admit air as needed.

Apply manufacturer-recommended lubricants to moving parts (hinges, springs) to reduce friction and prevent wear.

Immediately replace severely worn or damaged components like springs, gaskets, or seals.

Maintain an inventory of spare parts to minimize downtime during maintenance and repairs.
