Stainless Steel Actuator Retrofitting Guide
Compatibility analysis and implementation best practices
1Mechanical Compatibility
Mounting Standards: ISO 5211 flange compatibility enables direct replacement of 1990s carbon steel actuators on butterfly valves.
Undersized actuators fail in high-pressure systems (10 bar steam lines)
2Environmental Upgrades
3Air Supply Requirements
FRL Units Required: ≤5μm filtered air for pharmaceutical batching
Smart Controls: IoT sensors may need PLC/SCADA upgrades
4Physical Modifications
Scotch yoke designs may require new mounting plates
Stem Adaptation: Machine shop work needed for mismatched diameters
5Cost-Benefit Analysis
6Regulatory Compliance
Essential for petrochemical and food processing plants
Chemical Plant Retrofit
316L actuators replaced corroded carbon steel units on ball valves, eliminating annual failures in 20-year-old system.
