Control valve stroking speed and air supply pressure variation


have a question please, 

does the opening/closing time of the control valve vary with supply pressure variations. For example if pressure range is 5-8 (min&max). Will  stroking speed of valve be different if pressure is 5 bar instead of 8 or 7 etc? 

Thank you

  • Hi John,
    Yes, supply pressure variations can affect opening/closing time for a control valve. The expected variation in opening/closing time depends on several factors including the size/type of valve/actuator and the specific controls that are used. Can you give some details on your setup and performance requirements?
