Maintain detailed records of inspection dates, findings, and any necessary maintenance or repairs performed. This documentation helps establish a maintenance history and assists in tracking the valve’s performance over time.
Cleaning and Flushing
Regular cleaning and flushing of OEM valves are essential to remove debris, contaminants, scaling, or buildup that may accumulate and hinder their performance.
The frequency of cleaning depends on the nature of the media being controlled and the operating environment. Here are the general steps to follow:
- Preparation
Before cleaning, isolate the valve from the system by closing upstream and downstream isolation valves. Ensure proper lockout/tagout procedures are followed to prevent accidental activation during maintenance.
- External Cleaning
Use appropriate cleaning agents or solvents to remove dirt, grease, or other external contaminants from the valve body, actuator, and associated components. Follow the manufacturer’s guidelines regarding the compatibility of cleaning agents with valve materials.
- Internal Cleaning
For valves with removable internals, such as ball valves or plug valves, disassemble the valve and clean each component thoroughly. Use appropriate brushes, cloths, or tools to remove deposits or buildup. Take care not to damage any sealing surfaces or critical components during cleaning.
- Flushing
In some cases, flushing the valve and associated pipelines with a suitable flushing fluid may be necessary to remove particulate matter, sediments, or deposits that cannot be removed through regular cleaning. Consult with the valve manufacturer or a qualified professional to determine the appropriate flushing procedure.

If the OEM valve is actuated, follow the manufacturer’s recommendations for lubricating the actuator components, such as gearboxes, pneumatic cylinders, or electric motor drives.
Calibration
Calibration ensures that OEM valves operate accurately and in accordance with their specified performance parameters.
It involves verifying and adjusting the valve’s position, stroke, or flow characteristics to achieve the desired control or regulation.
Calibration requirements may vary based on the valve type and the level of precision required for the specific application. Here are the general steps involved in valve calibration:
- Valve Position Verification
If the valve is equipped with position indicators or limit switches, verify their accuracy by comparing the indicated valve position with the actual physical position. Adjust or replace faulty position indicators as necessary.
- Stroke Verification
For control valves or valves with defined stroke lengths, verify the valve’s stroke length by measuring the actual distance the valve travels from fully closed to fully open. Adjust the stroke length, if required, to match the desired specifications.
- Flow Characteristic Verification
In applications where the valve’s flow characteristic (e.g., linear, equal percentage, or modified) is crucial, use appropriate measuring instruments to determine the actual flow rate at different valve positions. Compare the measured data with the expected flow characteristic and adjust the valve accordingly.
- Actuator Calibration
For actuated OEM valves, calibrate the actuator to ensure proper response to control signals and accurate positioning of the valve. Follow the manufacturer’s instructions or consult with a qualified professional to perform actuator calibration.
