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

FEATURES

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

BENEFITS

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