Valve Terms
  • Breaking Pressure:
    The minimum pressure required to produce flow through a valve.
  • Duty Cycle:
    100% duty cycle is defined as continuous operation without any damage occurring. For intermittent duty cycle (<100%), alternate energized and de-energized state at regular intervals to allow the valve to completely cool down to room temperature.

    F = active concentration / total concentration
  • Flow Patterns:
    A diagram showing how flow can be directed using a particular valve. (See the "Flow Patterns" box below for further explanation.)
  • Normally Closed:
    Valve stays closed in de-energized state; opens when energized.
  • Normally Open:
    Valve stays open in de-energized state; closes when energized.
  • Pressure Differential or Pressure Drop:
    The difference between the inlet and the outlet pressure through a valve. The outlet pressure is lower than the inlet pressure due to the restriction caused by the valve.
  • Three-Way Valve:
    Has three ports. Depending on the particular valve, all three ports may be open, two ports may be open, or all ports may be closed.
  • Two-Way Valve:
    Has a single inlet port and a single outlet port. Brass Valves Factory Selection Guide
