Flow Controls

Small Engine - Flow-Controls

Flow Controls

  • Flexible rubber component sits in a pocket in the flow path
  • As pressure increases, the rubber deforms to reduce the center hole size
  • Rubber material properties and shape result in constant rate of flow
  • Typical useful pressure range is 20 to 120 psi (138 to 827 kPa)
  • Retaining ring should not apply axial force but only prevent misorientation
  • Each control is designed to work with a specific pocket shape
  • New center post design for superior performance
  • Some very low rate controls (drippers) use a flat stock design
