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.
