Netafim 1 1/2in Pressure Regulator 65 psi

Netafim PRV 2000 1 1/2 Inch Irrigation Pressure Regulator, 65 psi

High pressure zones still need a ceiling, especially when they are fed by a booster pump or a well that surges. This Netafim PRV 2000 body caps the outlet at 65 psi, or 4.5 bar, the highest preset Netafim offers in the series. Its 1 1/2 inch body carries two regulating units that share 11 to 35 gallons per minute. The inlet accepts up to 145 psi, or 10 bar, while the outlet stays at its preset. Each unit is a sealed cartridge built around a rubber diaphragm and a stainless steel spring and screw. Units come out in the field with a screw and interchange across every PRV 2000 body size. That makes it simple to drop the zone to a lower preset later if the heads change. A built-in indicator shows when the regulator has reached its outlet pressure. Male threads on both ends connect to female fittings at the header or riser. The body is non-corrosive plastic and brass that tolerates fertilizers and chemicals in the water. The diaphragm seal is tight, so the regulator stays dry at full load.

Protecting Overhead Sprinkler Zones and Mainlines

Impact sprinklers, rotors and large spray nozzles often run at higher pressure than drip emitters. Placing this regulator at the head of such a zone keeps pressure surges from distorting spray patterns. It also limits stress on pipe, risers and fittings when supply pressure creeps up at night. Check the rated pressure of the heads before choosing this preset. Next, confirm the zone flow sits between 11 and 35 GPM, for example 10 heads at 3 GPM for 30 GPM in total. The inlet needs the outlet setting plus the head loss across the regulator at that flow. Netafim publishes head loss curves for the PRV 2000 bodies so the supply can be sized ahead of installation. Install the regulator after the filter and zone valve, before the first riser. Flush the main before connecting so grit does not settle on either diaphragm. Tape the male threads and tighten until the joints stop weeping. On startup, compare the indicator with a downstream gauge to confirm the zone is holding.
