Application

Tips: Pneumatic Globe Valve Use Tips

Stable Gas Supply: Ensure that the pneumatic shut-off valve gets enough gas supply to ensure normal opening and closing operation of the valve.
Valve Operation Status Monitoring: Regularly check the operation status of the valve to ensure that the spool movement is free, no jamming or abnormal sound. If there is any abnormality, carry out maintenance in time.
Prevent Overloading: Avoid overloading operation to prevent damage to the pneumatic actuator or valve due to improper operation.
Prevent Pollution: Keep the working environment clean, prevent pollutants from entering the valve body, so as not to affect the normal movement of the valve spool.
Regular lubrication: Regular lubrication of the key parts of the pneumatic actuator to ensure the long-term reliable operation of the valve.
Avoid Freezing: In cold environments, take anti-freezing measures to prevent the pneumatic stop valve from icing and affecting normal use.
Pay Attention to Safe Operation: Operators should operate in accordance with relevant regulations to avoid safety accidents.
