M Series Pressure Regulators

For Agriculture Irrigation Systems

Accurate pressure regulation at an economical price.

PSI-M series regulators hold outlet pressure at a preset level. Regulated outlet pressures are available from 15 to 50 psi / 1.0 to 3.4 bar. As either inlet pressure or flow changes, the outlet pressure remains relatively constant.


  • Preset outlet pressure regulators
  • 3/4 in / 20 mm female inlet and outlet
  • Choice of 6 outlet pressures
  • Diaphragm operated
  • Use in above- and below-ground applications
  • Manufactured from rugged engineering-grade plastic
  • Stainless steel spring


Recommended for most operating conditions. This series is designed to withstand surges up to 100 psi / 6.8 bar greater than the rated outlet pressures, where high inlet pressures are combined with high flows.
  • • Flow Range - 2-10 gpm (0.5-2.27 m3/hr, 0.13-0.63 l/s)
