When is industrial valve maintenance required ?

Control Valve is the heart of the system that regulates flow, pressure and temperature in industrial automation lines. Whether operating in hot steam, compressed air, chemicals or wastewater, industrial valves must operate accurately and stably to ensure production efficiency. However, over time, valves will face many factors that cause wear, deviation or deterioration of control function. At that time, professional valve maintenance is mandatory to help prevent machine downtime, reduce energy loss and avoid system safety risks.

Signs that it's time for valve maintenance or repair

• Slow response valve, not reaching required opening/closing stroke

• Gas, vapor, or liquid leaks at stem, seat, flange, or actuator

• Unstable or fluctuating pressure or flow

• Loud noise, strong vibration when regulating flow

• Positioner 4-20 mA signal deviation, loss of control linearity

• Actuator has weak compression force, diaphragm/piston wear

• Dirt, cavitation, trim and seal corrosion

The ideal time to call for professional valve maintenance service

✔ Periodically every 6-12 months for continuously operating factories
✔ After peak production period, the system is overloaded for a long time
✔ When the medium or operating conditions (temperature/pressure/flow) change
✔ Before a major shutdown occurs to avoid unplanned downtime
✔ When a regulatory error is detected that affects product quality
✔ When operating costs (gas/electricity/steam energy) increase abnormally
✔ When the working environment is highly corrosive or contains impurities

Outstanding benefits of proper industrial valve maintenance

• Restore control accuracy to original

• Increase valve life, reduce replacement costs

• Optimizing energy and compressed air consumption

• Vibration reduction - noise, anti-shock pipeline pressure

• Ensure operational safety meets industry standards

• Reduce recurring problems with extensive testing and calibration

Control valve repair service not only helps businesses save 30-60% of costs compared to investing in new valves , but also ensures optimal control accuracy, safe operation and prolongs the life of the automation system . This is a mandatory service for factories using control valves that operate continuously, requiring high calibration and fast response.
