Each system in an industrial location, there is an oil refinery, power plant or chemical function, uses valves to maintain flow, regulate pressure and secure safey during operation. Surprisingly, one of the biggest problems with faults comes from the equipment lack of proper maintenance on the valve.
If the valve is not inspected, served or repaired in time, they can cause systems for systems, disabilities and severe leaks. At the same time, the preventive valve maintenance can improve the energy efficiency of construction operations during maintenance, expand the lifestyle of industrial valves and maintain operational continuity.
This article explains the process of tackling heavy equipment and corrosion, and other operational downtime, specifically through the lens of maintenance.
The Importance of Industrial Valves
An industrial valve forms the most critical part of any piping system by controlling the flow of any fluid, gas, or even slurry. Service valves, gas calibration valves, and control valves are a few of the different valve types used to control pressure and process flow in a system.
Corrosion and mechanical fatigue are common issues faced by valves especially when subjected to high pressure, temperature, and complex chemicals. Any valves, especially industrial valves, are very susceptible to wear and if not checked and maintained on time, will become a large expense, both on repairs and possible safety issues.
System efficiency and entire operational lifespan are both positively impacted with long lasting operational systems when valves are maintained structurally.
Reasons Why Regular Valve Maintenance Is Essential
1. Avoids Sudden Downtime
Performing periodic checks and maintenance on valves allows engineers to take swift, corrective action to wear or corrosion before failures occur. This ensures better reliability and avoids costly shutdowns.
2. Helps in Prevention of Corrosion on Tanks
Corrosion in valves, pipes, and tanks is a pernicious problem in the chemical and petrochemical industries. The prevention of leakage, along with a longer system lifespan, is attainable with proper valve maintenance of valves along with tank corrosion prevention.
3. System Performance is Enhanced
Controlled pressure and flow in a system also guarantees the reliability of the system. The maintenance of a service valve together with a well maintained system is likely to attain enhanced energy efficiency, reduced wear, and consistent product quality.
4. Safety and Legal Compliance are Guaranteed
Shut off valves, especially in high risk environments, is crucial to improve safety. Inadequate maintenance results in dangerous leaks and ruptures along with gas calibration valves which could also result in explosions. Compliance, as well as operational safety, is assured with periodic valve maintenance.
Standard Maintenance Procedures for Valves
Basic Valve Inspection
Routine valve inspection is monitoring for leakage, corrosion, and any signs of wear. Ultrasonic and pressure tests should be utilized for more severe cases.
Oil and grease should be added to moving components to reduce possibility of seizing and the friction.
Valve Spring Tester
Valve Spring Tester assesses the amount of pressure produced by springs to guarantee the spring is shutting and sealing properly. Leaks may be produced due to weak springs, causing the flow to be inaccurate.
Valve Repair and Replace
Valve repair immediately saves money and time especially when the problem is minimal. Replacing a valve is the best option for systems that no longer show signs of corrosion.
The Maintenance Role of Gas Calibration Valves
Gas calibration valves are maintained to ensure compliance with the safety of the process system. Having system inefficiencies and valve drift means the valves have to be cleaned and repaired.
The Maintenance and Prevention of Tank Corrosion
Corinable tanks that are protected from being damaged can be valves added to corrosion resistant for further protection. To preserve the tank and storage system, protective coatings, high quality materials and anti-forest valves should be used. If the storage system contains corrosive material, a lined valve can be used to improve reliability.

Steps to Develop an Effective Valve Maintenance Program
- Set schedules: A calendar timed according to each valve type and working conditions.
- Train technicians: Attending to repairs will also require learning the use of a valve spring tester.
- Log maintenance: A logbook can be used to file inspection results.
- Maintenance of Standards: Always use certified industrial valves.
- Anticipate problems: Adopt predictive maintenance whenever possible by using IoT technology.
Benefits of Good Valve Maintenance
- Maintenance on valves will reduce breakdowns by 50%.
- Have the plant become more reliable.
- Equipment will have longer periods of use.
- Improve the level of safety and overall efficiency.
FAQ’s on Valve Maintenance and the Lifetime of the Equipment
Q1. Why should we do valve maintenance?
A1. To do cost-effective operation valve maintenance is to keep industrial valves working in good conditions by preventing mechanical failures, leaks, and corrosion, which may lead to costly downtimes.
Q2. What is the frequency of valve inspection?
A2. Most plants should have a valve inspection done in intervals of 6 months to 12 months depending on the process conditions, type of fluid, and the frequency of operation.
Q3. What tools can be used during valve testing?
A3. Valve spring tester, torque wrenches, and ultrasonic sensors. Also, leak detectors can be used during testing valve performance and integrity.
Q4. How does valve maintenance help in the prevention of tank corrosion?
A4. It is because of valve maintenance that leaks and exposure of fluid is minimized which means that the chances of empanelling corrosion on adjacent tanks and pipes are minimized too. This is still in support of tank corrosion prevention.
Q5. What is the difference between valve repair and valve replacement?
A5. Valve repair usually addresses issues of minor damage, wore out seals, and calibration problems however replacement is mandatory when the valve body and or components are in a state of severe corrosion and structural disintegration.
Q6. Are gas calibration valves repairable?
A6. Certainly, gas calibration valves are repairable and can be recalibrated, when they out of a given tolerance. Cleaning and regular inspection help avert costly replacement.
Q7. How does maintenance enable plant reliability?
A7. It is the prolonged valuable time that valves are operational which translates in to pressure regulation steady enough to mitigate chances of stops. That is also why valves are controlled in maintenance for the reliability of the entire plant.
Conclusion
All valves with diesel gas kept in tanks for hours or days are also kept for pressure relief to bolster valve maintenance on the equipment. This keeps valves operational and uptime safe for the entire plant.
The maintenance does curb the chance of corrosion and leaks in the equipment valves however loss in process reliability is built and measured. That is why selling plants for valve maintenance is as much as is done or needed for smooth process operations.
The maintenance doesn’t raise, however, supports safe process operation disbursing a plant for the action valve to fortify reliability and operational advancement. The maintenance doesn’t prolong operation time more so aligns with the steps that automate plant operation, minimizing manual valve control. The steps actively smooth operation rhythms.
Any operational technique will maximize the time tanks with diesel gas endure, so lost time to curb process reliability is balanced with smooth valve sellers.
