What are some maintenance methods for pneumatic coaxial valves?

Jan 17,2024

As a crucial component in industrial automation control, the pneumatic coaxial valve's stable and lasting performance is vital to the smooth operation of production processes. However, even the best equipment requires proper maintenance, and pneumatic coaxial valves are no exception. This article details the maintenance methods for pneumatic coaxial valves to help ensure their normal operation and extend their service life.

I. Regular Inspection and Cleaning

Regularly inspect the valve's appearance to ensure its surface is free from cracks, rust, or other damage. If any abnormalities are found, they should be addressed and recorded promptly.
Regularly remove dust, dirt, and other impurities from the valve to maintain cleanliness. Pay particular attention to cleaning the dirt from the contact surfaces of the valve core and valve seat to prevent blockage or wear.

II. Maintain Good Lubrication

Regularly check the lubrication system of the pneumatic coaxial valve to ensure that the lubricating oil (grease) is sufficient and free of impurities.
Select the appropriate lubricating oil (grease) according to the equipment manufacturer's recommendations and replace it according to the specified cycle.
During lubrication, ensure that the oil passages are unobstructed to prevent blockage. If blockage occurs, clean it promptly.

III. Check Sealing Performance

Regularly check the sealing materials of the pneumatic coaxial valve, such as O-rings and gaskets, to ensure that they are intact and show no signs of aging. If damaged or aged, they should be replaced promptly.
With the valve closed, observe whether the valve seat contact surface is tightly fitted. If leakage is present, adjust the sealing material or replace the damaged seals.

IV. Check Pneumatic Device

Regularly check the pneumatic device of the pneumatic coaxial valve, including the air source, air ducts, and solenoid valve, to ensure its normal operation and absence of leaks.
Regularly clean the air ducts to prevent blockage or wear. If damaged or aged, they should be replaced promptly.
Check the operating status of the pneumatic components. If any abnormalities are found, repair or replace them promptly.

V. Maintain Operational Records

Record the operating status of the pneumatic coaxial valve, including operating time, working pressure, and temperature parameters.
