  • Motor Actuated Valve Application Guide Ball Valves
    gallons of water (at 60 F) that will pass through the valve in one minute with a differential pressure across the valve of 1 PSI. A valve s Cv is unique to the size, angle of opening and manufacturer s style. The information to consider in determining the Cv includes: Table A. Variable. Water. Steam
  • Selection Considerations for Control Valves Versus Regulators
    that can be measured and compared to a set point can be controlled. Also, it is necessary to keep in mind, irrespective of the parameter being controlled (the controlled variable), that the control valve itself can only change the flow rate.

  • Selecting Valves for Variable Flow Hydronic Systems (.pdf)
    Valves, such as common globe, butterfly, and ball valves, that performed satisfactorily for constant flow or variable flow primary-secondary systems generally are not satisfactory for primary-only variable flow systems because of the great variations in differential pressures across modulating
  • Co-Simulation Analysis of Transient Response and Control for Engines with Variable Valvetrains (.pdf)
    Modern engines are becoming highly complex, with several strongly interactive subsystems - - variable cam phasers on both intake and exhaust, along with various kinds of variable valve lift mechanisms. Isolated component models may not yield adequate information to deal with system-level
