When using pneumatic valve operators it is important to know the design requirements. These tables provide operating limits as well as flow coefficients and stem travel.

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. .
