Netafim™ 2-Unit Pressure Regulator - 1.5in - 12 PSI - 11-35 GPM

High-Flow Pressure Regulation for Large Irrigation Zones

The Netafim™ 2-Unit Pressure Regulator delivers consistent 12 PSI outlet pressure across an 11-35 GPM flow range — making it the right choice for large irrigation zones, main distribution lines, and high-flow commercial systems where smaller regulators can't handle the volume. The dual regulating unit design provides rapid response to pressure fluctuations, and the corrosion-resistant materials ensure long-term reliability in systems handling fertilizer solutions and chemical additives. A field-replaceable sealed regulating component simplifies service without removing the regulator body from the line.

Key Features & Benefits

• Constant 12 PSI outlet pressure — protects downstream emitters and maintains uniform delivery across the zone regardless of supply pressure variation.
• 11-35 GPM high flow range — handles the volume demands of large commercial irrigation zones and main distribution lines.
• 1.5in connection — sized for large-diameter irrigation mains and commercial lateral lines.
• 2-unit regulating design — dual regulating units provide fast, stable response to pressure changes across the full flow range.
• Corrosion-resistant materials — handles fertilizer solutions, chemical additives, and continuous irrigation service without degradation.
• Field-replaceable sealed regulating unit — service the regulator on site without removing the body from the irrigation line.

Who Should Use This

Commercial greenhouse operators, large-scale irrigators, and hydroponic facility managers who need reliable pressure regulation at 12 PSI across high-flow main or zone lines.

Compatibility

1.5in connection. Outlet pressure: 12 PSI. Flow range: 11-35 GPM. For drip and sprinkler irrigation systems requiring pressure regulation at this size and flow range.

Frequently Asked Questions

Why use a 2-unit regulating design?

The dual regulating units work together to provide faster, more stable pressure response across the wide 11-35 GPM flow range compared to single-unit designs at high flow rates.

How is the sealed regulating unit replaced in the field?

The sealed unit can be exchanged without removing the regulator body from the pipeline, reducing downtime and simplifying service. Refer to Netafim documentation for the service procedure.

Can this regulator be used for both drip and sprinkler systems?

Yes — the Netafim 2-unit regulator is designed for both drip and sprinkler irrigation systems within its rated pressure and flow parameters.

What is the maximum inlet pressure this regulator can handle?

Refer to the Netafim specification sheet for the maximum rated inlet pressure for the 1.5in 12 PSI 2-unit model.
