Efficient Maintenance of Electric Ball Valves and Actuators
On this page

Electric ball valves, driven by electrical power, are crucial equipment for valve opening, closing, and fluid regulation. Widely used across various industrial settings, their primary functions include isolating or connecting media within pipelines and precisely adjusting fluid flow and pressure. As integral components of industrial automation and process control, the stable operation and long-term reliability of electric ball valves are inseparable from proper maintenance.
 

Methods for Maintenance of Electric Ball Valves


Store electric ball valves indoors in a dry and well-ventilated area. Seal both ends of the pipelines to prevent dust and debris ingress. For long-term storage, conduct regular inspections, clean away debris, and apply rust preventive oil on exposed surfaces to ensure equipment longevity and reliability.
 

1. Storage Environment Management


Store electric ball valves in a dry, well-ventilated indoor area.
Seal both ends of the pipelines to prevent dust and debris ingress.
Conduct regular inspections for valves stored long-term, cleaning away contaminants and applying rust inhibitor on exposed surfaces to maintain equipment integrity.
 

2. Routine Equipment Inspection


Regularly inspect all components of the electric ball valve after installation.
Check valve bodies, covers, seals, and operational components for signs of wear, corrosion, or damage.
Ensure bolts on flanges and supports are tight to prevent potential equipment malfunction due to loosening.
 

3. Packing Gland and Stem Protection


Verify that packing glands are correctly installed without misalignment or insufficient tightening.
Install stem protection covers, especially in environments prone to dust or moisture, to safeguard against corrosion and mechanical damage.
 

4. Accessory and Label Examination


Periodically examine valve scales and labels to ensure they are legible, accurate, and intact.
Inspect auxiliary components such as lead seals, caps, and pneumatic attachments for functionality and condition.
 

5. Insulation Jacket Inspection


Inspect insulation jackets regularly to ensure they are free from dents or cracks.
Maintain the integrity of insulation jackets to support stable valve operation, especially in environments with low temperatures.
 

Special Requirements for Electric Ball Valve Actuators


Electric ball valve actuators have specific requirements for torque limitation and rotational angles. When selecting actuator specifications, determine control torque based on actual application requirements to avoid motor overload, ensuring equipment stability and lifespan.
 

1. Torque and Operational Limits


Torque Requirements: Determine and set appropriate torque limits based on the specific application and valve size. This prevents motor overload and ensures smooth operation.
Operational Adjustments: Regularly check and adjust torque settings to maintain optimal performance and prevent mechanical stress on the actuator.
 

2. Environmental Adaptability


Temperature Range: Control the operating temperature of electric actuators within specified limits (typically -25°C to 70°C). This ensures reliable operation and prevents damage from extreme environmental conditions.
Explosion-proof Requirements: For hazardous environments, such as those with flammable gases or vapors, choose explosion-proof actuators to mitigate safety risks.
 

3. Maintenance Practices


Regular Inspections: Conduct routine inspections of actuator components, including motors, gears, and electrical connections. This helps identify potential issues early and ensures uninterrupted operation.
Lubrication: Maintain proper lubrication of moving parts according to manufacturer guidelines to reduce friction, wear, and potential failures.
Seal Integrity: Check and replace seals periodically to prevent fluid leaks, which can compromise valve performance and safety.

When performing maintenance and care for electric ball valves, always adhere to correct operational procedures and regular inspections. By following these guidelines, you can effectively prolong the service life of electric ball valves, enhance equipment reliability and operational efficiency, and reduce downtime and maintenance costs caused by failures. Ensuring suitable operating conditions and conducting regular maintenance and inspections will help maintain stability and safety of equipment across various industrial applications.
