Routine Inspections

Regular inspections are crucial for identifying any signs of wear, damage, or performance issues in OEM valves.

The frequency of inspections may vary depending on the valve type, application, and operating conditions.

However, a general guideline is to conduct inspections at least once every six months or as recommended by the valve manufacturer. Here are the key steps to follow during inspections:

  • Visual Inspection

Begin by visually examining the valve body, actuator, connections, and other components for any visible signs of leaks, corrosion, cracks, or physical damage. Pay close attention to the valve stem, seals, gaskets, and fasteners.

  • Functionality Check

Operate the valve through its full range of motion to ensure smooth operation without any sticking, binding, or excessive resistance. Verify that the valve opens and closes fully and that the actuator responds correctly to control signals.

  • Leak Detection

Inspect for any leakage around the valve body, connections, or seals. Use appropriate methods, such as visual inspection, dye penetration testing, or pressure testing, to identify any leaks accurately.

  • Valve Position Verification

If the valve is equipped with position indicators or limit switches, verify that they accurately indicate the valve’s open and closed positions.

  • Documentation

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.

  • Reassembly

Once cleaning and flushing are complete, carefully reassemble the valve, ensuring proper alignment, tightness of fasteners, and correct installation of seals or gaskets. Follow the manufacturer’s instructions for reassembly to ensure proper functionality.


Proper lubrication is essential for the smooth operation and longevity of OEM valves. It minimizes friction, reduces wear and tear, and helps maintain the integrity of sealing surfaces.

Here are the key steps to follow for valve lubrication:

  • Lubricant Selection

Consult the valve manufacturer’s recommendations to determine the appropriate type of lubricant for the specific valve type, materials, and operating conditions. Use only compatible lubricants to avoid damage to valve components.

  • Lubrication Points

Identify the lubrication points on the valve, which typically include the valve stem, thrust bearings, and other moving parts. Follow the manufacturer’s guidelines regarding the quantity and frequency of lubrication.

  • Cleaning

Before applying lubricant, ensure that the lubrication points are clean and free from debris or old lubricant residue. Use appropriate cleaning methods, such as wiping or brushing, to prepare the surfaces.

  • Lubricant Application

Apply the recommended lubricant to the identified lubrication points using a suitable applicator or by following the manufacturer’s instructions. Avoid over-lubrication, as excessive lubricant can attract contaminants or interfere with valve operation.

  • Actuator Lubrication

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 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.

  • Documentation

Maintain detailed records of calibration activities, including the calibration dates, adjustments made, and any deviations from the expected performance. These records serve as a valuable reference for future maintenance and troubleshooting.


In the event of valve malfunctions or operational issues, troubleshooting is necessary to identify the underlying problems and implement appropriate corrective measures.

Here are some common troubleshooting steps for OEM valves:

  • Identify the Issue

Carefully observe and analyze the valve’s behavior to determine the nature of the problem. Isolate the issue to the valve itself or investigate if external factors, such as control signals or supply pressures, are causing the problem.

  • Check for Obstructions

Inspect the valve body, seat, or internal components for any obstructions, such as debris, foreign objects, or scale buildup. Remove any blockages that may hinder proper valve operation.

  • Examine Seals and Gaskets

Inspect the valve’s seals and gaskets for signs of wear, damage, or leakage. Replace worn-out or damaged seals to ensure proper sealing and prevent leakage.

  • Evaluate Actuator Performance

If the valve is actuated, assess the actuator’s performance, including pneumatic or electric control systems, positioners, or solenoid valves. Verify that the actuator receives appropriate control signals and responds correctly.
