Preset to 30 psi, the Hunter PMR-30-MF Pressure-Master Regulator stabilizes downstream pressure for medium-flow irrigation systems. Designed for inline installation, this compact regulator maintains a consistent outlet pressure to protect drip lines, sprinklers, and micro-irrigation components from pressure fluctuations.

  • Preset outlet pressure: 30 psi (2.07 bar); requires inlet at least 5 psi higher than outlet.
  • Flow range: 2–20 gpm (454–4543 L/h), suitable for medium-flow applications.
  • Connections: 1-inch female NPT inlet and outlet for straightforward inline plumbing.
  • Maximum inlet pressure: 110 psi (7.58 bar); pressure-tested for reliable performance.
  • Low hysteresis and friction losses; recommended for outdoor use (not NSF certified).

Easy to install and service, the PMR-30-MF reduces wear on emitters and improves uniformity across irrigation zones. For best results, install with the flow direction arrow aligned with system flow and avoid placing the unit where debris can accumulate; install upstream filters where needed.
