Globe Valve Vs Check Valve: A Deep Comparison Of Maintenance Costs And Optimization Solutions

The maintenance costs of industrial valves are often underestimated. Through 200 sets of real operation data, we conduct a comparative analysis of the full lifecycle costs of two types of valves.

 

Maintenance Data Comparison

● Globe Valve:

● Average Annual Maintenance Frequency: 3-4 times

● Common Failures: Packing leakage (42%), stem sticking (35%)

● Single Maintenance Cost: 800-1500 yuan

● Check Valve:

● Average Annual Maintenance Frequency: 0.5-1 time

● Main Issues: Disc wear (68%)

● Single Maintenance Cost: 300-600 yuan

● Optimization Recommendations

 

Globe Valve Maintenance Plan:

● Use graphite packing to extend seal life.

● Lubricate the valve stem every quarter.

● Install a torque monitoring device.

 

Check Valve Maintenance Strategy:

● Inspect the valve disc sealing surface annually.

● Install wear-resistant liners at vulnerable parts.

● Use an online monitoring system.

 

After implementing the optimization plan, a certain petrochemical company reduced its valve maintenance costs by 37%, and the equipment availability increased to 99.2%.
