Netafim™ High Flow Pressure Regulator - 3/4in - 35 PSI - 4.5-17.6 GPM

Stable 35 PSI Regulation for Mid-to-High Flow Irrigation Systems

The Netafim™ High Flow Pressure Regulator maintains a consistent 35 PSI outlet pressure across a 4.5-17.6 GPM flow range, providing the pressure stability needed for reliable emitter performance in mid-to-high flow drip and sprinkler irrigation systems. Quick inlet pressure response prevents pressure spikes from reaching downstream emitters, and corrosion-resistant materials ensure long-term durability in systems running fertilizers and chemical additives. The 3/4in connection fits standard irrigation mainline and zone valve outlets for straightforward installation.

Key Features & Benefits

• Constant 35 PSI outlet pressure — protects downstream emitters from over-pressure, ensuring uniform delivery and extended emitter life.
• 4.5-17.6 GPM flow range — handles mid-to-high flow zones including larger drip manifolds and sprinkler systems.
• Quick inlet pressure response — rapidly compensates for supply pressure variation to maintain consistent outlet pressure throughout the irrigation cycle.
• Corrosion-resistant materials — designed for continuous use with fertilizer solutions and chemical additives without component degradation.
• 3/4in connection — standard size for zone valve outlets and lateral line headers in most irrigation installations.

Who Should Use This

Commercial growers and irrigation professionals running 3/4in zone lines with mid-to-high flow drip or sprinkler systems who need stable 35 PSI outlet pressure protection for consistent emitter performance.

Compatibility

3/4in connection. Outlet pressure: 35 PSI. Flow range: 4.5-17.6 GPM. For drip and sprinkler irrigation systems requiring regulated pressure at this size and flow range.

Frequently Asked Questions

How does this differ from the Netafim Low Flow Pressure Regulator?

The High Flow model handles 4.5-17.6 GPM for larger zones; the Low Flow model handles 0.25-4.4 GPM for small drip and micro-emitter arrays. Both are available in 15 and 35 PSI outlet pressures.

Is this regulator suitable for fertigation systems?

Yes — the corrosion-resistant materials are designed to handle fertilizer solutions and chemical additives in fertigation applications.

Can I use this regulator with a sprinkler system?

Yes — the High Flow Pressure Regulator is designed for both drip and sprinkler irrigation systems within its rated parameters.

What is the maximum inlet pressure rating?

Refer to the Netafim specification sheet for the maximum rated inlet pressure for the 3/4in 35 PSI High Flow model.
