Netafim™ Low Flow Pressure Regulator - 3/4in - 0.25-4.4 GPM - 15 PSI

Consistent Outlet Pressure for Low-Flow Drip and Micro-Irrigation Systems

The Netafim™ Low Flow Pressure Regulator maintains a steady 15 PSI outlet pressure across a 0.25-4.4 GPM flow range, ensuring reliable, uniform performance in low-flow drip lines, micro-irrigation systems, and emitter arrays where pressure variation would compromise delivery uniformity. Built with corrosion-resistant materials to handle fertilizer solutions and chemical additives, and featuring a sealed regulating component designed for field replacement when service is needed — keeping maintenance straightforward without removing the regulator body from the line.

Key Features & Benefits

• Constant 15 PSI outlet pressure — stabilizes downstream pressure at 15 PSI regardless of inlet pressure variation, protecting emitters and ensuring uniform flow.
• 0.25-4.4 GPM flow range — suited for low-flow drip systems, individual plant drip stakes, and small micro-irrigation zones.
• Corrosion-resistant materials — withstands fertilizer injections, chemical additives, and the demands of continuous irrigation use.
• Field-serviceable sealed regulating unit — the regulating component can be replaced in the field without removing the entire regulator body, simplifying service.
• Quick response to pressure changes — rapidly compensates for inlet pressure fluctuations to maintain consistent outlet pressure throughout the irrigation cycle.
• 3/4in connection — fits standard irrigation mainline and lateral line plumbing for straightforward installation.

Who Should Use This

Drip irrigators, container growers, and greenhouse operators running low-flow emitter systems who need stable outlet pressure protection to ensure uniform delivery across every emitter in the zone.

Compatibility

3/4in connection. Outlet pressure: 15 PSI. Flow range: 0.25-4.4 GPM. Compatible with Netafim and standard drip irrigation systems within the specified pressure and flow parameters.

Frequently Asked Questions

What happens if my inlet pressure exceeds the regulator's rated range?

The regulator is designed to reduce inlet pressure to the set 15 PSI outlet regardless of how much higher the inlet pressure is, within the regulator's rated maximum inlet pressure. Check the Netafim specification sheet for maximum inlet pressure limits.

Can the sealed regulating unit be replaced without a plumber?

Yes — the sealed unit is designed for field replacement by irrigation technicians without specialized tools or removing the regulator body from the line.

Why choose a low flow regulator over a standard model?

Low flow regulators are optimized for the 0.25-4.4 GPM range typical of drip stakes and micro-emitter arrays. Standard regulators may not regulate accurately at very low flow rates.

What is the difference between the 15 PSI and 35 PSI versions?

The outlet pressure setting differs — 15 PSI is typical for pressure-compensating drip emitters rated at lower pressures; 35 PSI suits emitters and systems designed for higher operating pressures. Match the regulator to your emitter specifications.
