Daily Maintenance and Operating Environment of Needle Valves
Release date:
2022-01-11
Needle valves should have their oil level in the oil level indicator checked regularly, with the oil mist lubricator replenished as needed. The condensate and contaminants accumulated at the bottom of the moisture filter cup should be drained periodically. Verify the air supply pressure and adjust the flow rate via the one‑way throttle valve to ensure the valve has sufficient actuation force and operates smoothly. Inspect the inspection ports for air or water leaks; if leaks are detected, replace the seals promptly. During routine operation, needle valves require regular checks of the oil level in the oil level indicator, timely refilling of the oil mist lubricator, and periodic removal of condensate and debris collected at the bottom of the moisture filter cup.
