Rain Bird Pressure Regulators

PSI-M models are designed to withstand up to 6 bars greater than the rated outlet pressure, where high inlet pressures are combined with high flows.
PSI-M regulators hold outlet pressure at a pre-set level. The regulated pressure varies somewhat with flow (nozzle size), but is nearly constant with varying inlet pressure.
These regulators may be used on flows higher than indicated on the charts, but the outlet pressure may be lower than acceptable.

Features:

  • Preset outlet pressure regulators
  • Diaphragm operated
  • For use above or below ground
  • Choice of 6 outlet pressures
  • Stainless Steel Spring
