Valves play a crucial role in a wide range of
industries, ensuring the controlled flow of
liquids, gases, and slurries. Proper
installation, operation, and maintenance of
valves are essential to ensure optimal
performance and extend their lifespan. This guide
outlines best practices for valve maintenance to
help you achieve these goals.

Valve Installation
Pre-Installation Inspection
Before installing a valve, perform a thorough
inspection to ensure it is free from defects and
debris. Check for

• Proper valve type and size for the application.
• Any visible damage or wear.
• Cleanliness of the valve and pipeline.

Correct Installation Procedures

• Alignment Ensure the valve is correctly aligned
  with the piping system to prevent stress and
  potential leakage.
• Gasket Placement Use appropriate gaskets and
  ensure they are correctly positioned to avoid
  leaks.

4

• Tightening Follow manufacturer specifications
  for tightening bolts to avoid over-tightening or
  under-tightening, which can lead to leaks or
  damage.
• Support Provide adequate support to the valve
  and adjoining pipes to prevent undue stress on
  the connections.

Post-Installation Checks
After installation, perform the following checks

• Inspect for leaks around the valve and
  connections.
• Verify the valve operates smoothly and without
  excessive force.
• Confirm the valve is properly labeled and its
  position is clearly indicated.

5
Valve Operation
Understanding Valve Types and Their Functions
Different valves serve different purposes. Common
types include

• Gate Valves Used for on/off control.
• Globe Valves Used for regulating flow.
• Ball Valves Provide tight shut-off.
• Check Valves Prevent backflow.
• Butterfly Valves Suitable for large flow rates
  and low-pressure drops

6
Operational Best Practices

• Gradual Operation Operate valves gradually to
  avoid water hammer or sudden pressure changes.
• Position Awareness Know the fully open and fully
  closed positions to avoid over-operating the
  valve.
• Regular Testing Periodically operate valves that
  are normally left in one position to prevent them
  from seizing.

Common Operational Issues and Solutions

• Sticking Valves Lubricate and clean the valve.
• Leaks Check and replace seals or gaskets.
• Corrosion Apply appropriate anti-corrosion
  treatments and use compatible materials.

7
Valve Maintenance
Regular Inspection Routines

• Visual Inspections Look for signs of wear,
  corrosion, or leaks.
• Functional Tests Ensure the valve operates
  smoothly and effectively.
• Pressure Tests Verify that the valve maintains
  pressure without leaks.

Cleaning and Lubrication

• Cleaning Remove any debris or buildup from the
  valve body and moving parts.
• Lubrication Apply appropriate lubricants to the
  stem and moving parts to ensure smooth operation.

8
Troubleshooting and Repair

• Minor Repairs Replace seals, gaskets, and
  packing as needed.
• Major Repairs For significant damage, consult
  the manufacturer or a specialist for repair or
  replacement recommendations.

Record Keeping and Documentation
Maintain detailed records of all maintenance
activities, including

• Inspection dates and findings.
• Maintenance performed.
• Parts replaced.
• Any issues encountered and solutions applied.

9
Safety Considerations
Personal Protective Equipment (PPE)

• Wear appropriate PPE such as gloves, safety
  glasses, and protective clothing during
  installation, operation, and maintenance.

Safety Protocols During Maintenance

• Isolate the valve from the system before
  performing any maintenance.
• Depressurize and drain the system as necessary.
• Follow lockout/tagout procedures to ensure the
  system cannot be inadvertently activated.

Emergency Procedures

• Have emergency procedures in place for valve
  failures, leaks, or other hazardous situations.
• Ensure all personnel are trained in these
  procedures and know the location of emergency
  shut-off valves.
