What is the impact of regular maintenance on the failure rate of pneumatic butterfly valve

Reduce seal failure

Keep the sealing: check the state of the sealing parts during regular maintenance, and clean up the impurities and dirt on the sealing surface in time to prevent the deterioration of the sealing performance due to wear and corrosion. It will also replace the aging or damaged seals in time according to the need, so as to effectively avoid leakage and other faults caused by lax sealing, and prolong the service life of pneumatic butterfly valve.

Prevent deformation and aging: reasonable regular maintenance can ensure that the seal is in a good working environment, avoid the impact of long-term high temperature, high pressure and other harsh conditions to accelerate deformation or aging, so that the seal can always maintain good elasticity and sealing performance, reduce the probability of failure caused by seal problems.

Ensure the normal operation of the actuator

Optimize the pneumatic system: regularly maintain the pneumatic actuator, including checking whether the air source pressure is stable, whether there is leakage in the pneumatic line, and whether the filter is blocked. Ensure that the air source is clean and dry, which can effectively prevent impurities from entering the actuator and avoid problems such as insensitive and astringent butterfly valve action caused by pneumatic system failure, thereby reducing the failure rate.

Ensure the lubrication of mechanical parts: the mechanical transmission parts of the actuator, such as gears, rack, shaft and other regular lubrication, can reduce the friction between the components, prevent excessive wear caused by parts damage, so that the actuator can smoothly drive the butterfly valve open and close, reduce the failure of pneumatic butterfly valve caused by mechanical failure.

Detect and troubleshoot potential problems

Early problem detection: Regular maintenance will carry out a comprehensive inspection of the pneumatic butterfly valve, which can detect some potential problems in time, such as slight leakage of the valve, loose parts, abnormal electrical connections, etc. Fixing or dealing with these problems while they are still in their infancy greatly reduces the likelihood of failure by preventing them from getting worse.

Performance parameter calibration: Through regular maintenance, the performance parameters of the pneumatic butterfly valve can be calibrated and adjusted, such as the opening and closing time of the valve, stroke, torque, etc., to ensure that it works normally within the design range. The accuracy and stability of performance parameters help to reduce the valve failure caused by parameter deviation and improve the reliability of the system.

Keep the system clean

Prevent the accumulation of impurities: regular maintenance will clean the pneumatic butterfly valve and related pipelines to prevent the accumulation of impurities, dirt, rust and so on in the valve. These impurities may affect the normal opening and closing of the valve, resulting in lax sealing or component damage. Regular cleaning can keep the interior of the valve clean and reduce the failure caused by impurities.

Avoid the influence of media: for the pneumatic butterfly valve with corrosive or easy crystallization and other special media, regular maintenance can take corresponding protective measures, such as anti-corrosion treatment, prevent medium crystallization blockage, etc., to reduce the damage of the medium to the valve, and then reduce the occurrence of failures.
