Rain Bird PSI-M Series Pressure Regulators

The Rain Bird PSI-M Series Pressure Regulators are designed to maintain constant outlet pressure regardless of inlet fluctuations, ensuring optimal performance and uniform water distribution. Installed upstream of emitters or sprays, they protect irrigation components and improve system efficiency by preventing misting and over-pressurisation. Ideal for both drip and spray systems in residential and commercial landscapes.

Key Features:

Maintains consistent outlet pressure under varying inlet conditions
Available in multiple pressure ratings: 1.0, 1.5, 2.0, 2.8, and 3.5 bar
Designed for inline installation upstream of emission devices
Improves system performance and water efficiency
Prevents damage from high pressure or surging
Durable construction for long service life in all conditions

Product Highlights

• Built-in pressure regulation for controlled output

• ¾” female threaded inlet and outlet connections

• Available in five different outlet pressure ratings

• Diaphragm-actuated for consistent performance

• Designed for use both above ground and buried installations

• Constructed from high-strength, engineering-grade polymer

• Corrosion-resistant stainless steel spring mechanism

Performance Parameters

Operating Pressure Range

10 to 150 psi (0.7 to 10.3 bar)

Flow Range 2 to 22 gallons per minute (gpm)

Equivalent to:

• 0.5 to 5.0 m³/h

• 0.13 to 1.4 liters per second (lps)

Application Note

The PSI-M Medium Flow Regulator series is ideal for standard irrigation system pressures and flows. It is engineered to tolerate inlet pressure surges of up to 100 psi (6.8 bar) beyond its rated outlet pressure, making it suitable for systems where high inlet pressures and rapid flow changes are common.
