Air Operator Sizing Data : Pneumatic Valve Actuators
Air to Open Sizing Data for Piston and Diaphragm Operators.

FEATURES

• Required operator air pressure at various system pressures.
  
  
• Maximum operating pressure.
  
  
• Stem travel.
  
  
• Flow coefficients.
  
  
• Spring compression.
  

BENEFITS

These tables are used when design systems and specifying air actuated valves. The tables show the air pressure required to open valves, at different operating pressures, and for the different size operators.
