  • Principles of Solenoid Coil Design for Valves
    product range has been developed for the specialist scientific industry. The solenoid comes in two basic forms, one is for pulling and the other is for pushing. Which one is used depends on the method of operation required to actuate the valve itself. We will begin with the pulling version. When the coil
  • The What, How, Where and Why of Solenoid Valves
    , a minimum inlet pressure/differential pressure (typically 5 PSI) is required for the valve to operate. II. HOW do they operate? A. Direct-Acting - In Direct-Acting Solenoid Valves the energized coil magnetically pulls-up on the core, which is attached to the shaft and seat, thus overpowering
  • Fuel Efficiency Improvements from Lean, Stratified Combustion with a Solenoid Injector (.pdf)
    In light of the growing emphasis on CO2 emissions reduction, Delphi has undertaken an internal development program to show the fuel economy benefits of lean, stratified combustion with its outwardly-opening solenoid injector in a vehicle environment. This paper presents the status of this ongoing
  • How Some Supervisory and Leakage Currents Can Affect Today's Low-Power Solenoid Valves
    . Figure 1. I/O MODULE. FILTERS. LEAKAGE. CURRENT. SOLID-STATE. COIL. SWITCH. Affected low-power valves. Again, the main type of valve possibly impacted by an output module mismatch is the. low-power solenoid valve. A low-power coil operates at a much lower current than a standard solenoid valve
  • Voice Coil Motors
    Voice coil motors offer excellent control characteristics where linear actuation is required over short distances with electronic control systems. Comparison of the force characteristics vs displacement, and vs current, for voice coil devices and solenoid actuators shows the difference between

  • Pneumatics troubleshooting gets easier
    pneumatic-control system provides basic valve operation, as well as detailed monitoring of electrical solenoids, sensors, wiring, and connections. Called Drive Diagnostic Link (DDL), the system checks that every valve's supply voltage is within acceptable tolerances, solenoid coils operate properly
  • Micro-Dispensing Liquid Pump
    and lifetime requirements," Kaufmann says. "Using the solenoid versus the dc motor complicated the design, but in the final result is a more sophisticated control capability.". During pump operation, an electrical impulse energizes the solenoid coil and creates a magnetic field, which pulls
