High Pressure Performance of Ball Valve Pneumatic Actuators
Yes, ball valve pneumatic actuators can work under high-pressure conditions, but their performance depends on several factors:
Key Performance Factors
Actuator Design
Heavy-duty actuators with robust construction (e.g., piston-type or scotch-yoke mechanisms) are better suited for high-pressure applications than diaphragm-type actuators.
Material Strength
High-grade materials (stainless steel, hardened alloys) for the actuator and valve components ensure durability under extreme pressures.
Air Supply Pressure
Pneumatic actuators require sufficient air pressure (typically 4 - 7 bar, but some models handle up to 10 bar) to overcome high fluid pressures. Boosters may be needed for very high loads.
Seals & Lubrication
High-pressure seals (PTFE, elastomers) and proper lubrication prevent leaks and reduce wear.
Sizing
Proper actuator sizing (torque/thrust output) is critical to ensure it can operate the valve against high fluid pressures without stalling.
Conclusion
With the right specifications, pneumatic actuators can reliably control ball valves in high-pressure systems (e.g., oil/gas, chemical processing). Always consult manufacturer guidelines for pressure limits.
