A new constant flow valve for hydraulic sprayers ensures consistent nozzle pressure, even at low levels. This technology shows promise for improving vector control operations.

Area of Science:

  • Agricultural Engineering
  • Public Health Entomology

Background:

  • Hand-compression sprayers are widely used for pesticide application.
  • Maintaining consistent nozzle pressure is crucial for effective and uniform spray distribution.
  • Existing sprayers may exhibit pressure fluctuations affecting application efficacy.

Purpose of the Study:

  • To evaluate a commercial inline constant flow valve for hand-compression hydraulic sprayers.
  • To determine the valve's ability to maintain constant nozzle pressure down to a preset cut-out pressure.
  • To assess the valve's suitability for vector control applications.

Main Methods:

  • Testing of a commercial inline constant flow valve.
  • Integration with H.D. Hudson X-Pert 9.5-liter hand-compression sprayers.

  • Measurement of flow rates and pressure regulation capabilities.

    • Main Results:

    • The flow-control valve consistently maintained flow rates.
    • The valve successfully regulated pressure down to a preset cut-out level.
    • Consistent performance was observed with the tested sprayer model.

    Conclusions:

    • The tested inline constant flow valve effectively maintains consistent flow rates.
    • The valve demonstrates reliable pressure regulation in hand-compression sprayers.
    • This technology presents potential benefits for vector control operations.
