Maintaining Precision: Tips for Care and Maintenance of Rotary Globe Valves

Rotary globe valves are indispensable components in many industrial applications, where precise control of flow is critical. To ensure the longevity and reliability of these valves, proper care and maintenance are essential. In this blog, we will provide valuable tips and insights on how to maintain the precision of rotary globe valves, extending their lifespan and optimizing their performance.

Understanding the Importance of Maintenance

Maintenance is a proactive approach to preventing issues and preserving the functionality of rotary globe valves. Regular maintenance not only ensures the valves continue to operate precisely but also minimizes the risk of costly downtime and repairs.

Regular Inspection

Scheduled inspections are fundamental to identifying potential issues before they escalate. During inspections, look for signs of wear, corrosion, and leakage. Pay close attention to the valve's body, seat, disc, and stem. If any irregularities are detected, address them promptly to prevent further damage.


Proper lubrication is essential for the smooth operation of rotary globe valves. The stem and moving parts should be well-lubricated to reduce friction and wear. Choose the appropriate lubricant based on the valve's materials and the operating conditions. Regularly applying and monitoring the lubrication ensures consistent performance.

Cleaning and Flushing

Over time, rotary globe valves can accumulate debris and deposits that affect their functionality. Regular cleaning and flushing of the valve and the surrounding piping can prevent clogs and maintain optimal flow control. Use approved cleaning solutions and techniques to avoid damaging valve components.

Seal and Gasket Inspection

Leaks are one of the most common issues in control valves. Inspect the seals and gaskets for signs of wear or damage. Replacing worn-out seals and gaskets is a proactive way to prevent leaks and maintain precise control over flow.

Calibration and Testing

Regular calibration and testing of rotary globe valves are crucial for ensuring they perform as intended. These procedures help identify any deviations in valve operation and allow for adjustments to maintain precise control.

Corrosion Control

In industries where corrosion is a concern, applying anti-corrosion coatings or materials to valve components can extend their lifespan and maintain precision. Additionally, implementing proper cathodic protection systems can prevent corrosion in critical areas.

Record Keeping

Maintaining detailed records of maintenance and inspection activities is invaluable. It allows for the tracking of valve performance over time, identification of recurring issues, and the scheduling of proactive maintenance. Well-kept records also help with compliance and auditing requirements.

Training and Education

Ensure that maintenance personnel are well-trained and knowledgeable about the specific rotary globe valves in use. Regular training and education on proper maintenance procedures can minimize errors and enhance the precision of valve care.


Proper care and maintenance are essential for maintaining the precision and reliability of rotary globe valves in industrial applications. By implementing a proactive maintenance program and adhering to best practices, industries can ensure that these critical components continue to operate effectively, contributing to process efficiency and reducing the risk of costly downtime and repairs.
