  • How to Choose a Control Valve
    , valve sizing is not an exact science, but is the result of making the best selection from available options. Characterized "V" Ball valves provide the high precision throttling and rangeability needed for liquid and gas control ap-. plications, where a streamlined flow passage allows for high
  • Cyclic Operation of Fossil-Fueled Electric Power Generating Units (.pdf)
    temperatures if cycling down to low loads. Other. considerations include: * Changes in flue gas velocity. * Changes in pollutant loading. For the turbine-generator set, consideration must be given to: * Increased stresses and wear on valve components due to extended periods of valve throttling. * Bearing
  • Performance, Robustness, and Durability of an Automatic Brake System for Vehicle Adaptive Cruise Control
    on the wheel brake hydraulic. pressure is through ON/OFF control of the Prime and. lines. Delphi VIV technology provides the characteristic. Isolation Valves. Wheel pressure is increased by. of throttling the braking flow through the orifice of the. regulating the fluid supply to the pump through Prime
  • Key to Plant Optimization
    variability, more consistent product and better energy efficiency. To achieve better dryer performance, air and fuel flows must be controlled precisely and consistently throughout the process. Traditionally, pneumatic actuators have been used to control the various throttling dampers and valves
  • Sample System Design and Diaphragm Pumps
    is located at the pump outlet. Use of a relief valve or back pressure regulator will reduce the pump diaphragm. pressures, as in the case where a throttling valve is located. d at pump outlet; adding. filter(s) will also help system performance. Description of a system providing constant flowrate
  • Volumetric Efficiency and Pumping Torque Estimation and Compressor Recirculation Control of Turbocharged Engines (.pdf)
    intake manifold pressure (P_Int) is not used. as a VE load variable is because it does not take into. In order to better understand how VE changes with. account the effect throttling has on VE which results in. intake and exhaust pressure, GT-Power® simulations. incorrect VE modelling at altitude
  • Mechnical Vacuum Pump Selection Considerations for Ion Pressure Nitriding, Plasma Nitriding and Nitro Carborising (.pdf)
    by throttling the vacuum. pump system with a motorised control valve linked to the chamber pressure measurement. At the. process pressures not all of the ammonia is completely dissociated into nitrogen and hydrogen, and. so the resulting furnace atmosphere is a mixture which contains a significant amount
