Netafim 1 1/2in Pressure Regulator 35 psi

Netafim PRV 2000 1 1/2 Pressure Reducing Valve, 35 psi

Netafim's PRV 2000 series covers the regulators that sit at the head of a zone and absorb whatever the supply throws at them. This 1 1/2 inch version carries two regulating units and controls 11 to 35 gallons per minute. Its outlet is preset at 35 psi, or 2.5 bar, a firmer setting than most drip zones use. Supply pressure up to 145 psi, or 10 bar, can enter the inlet without moving the outlet. Each unit is a sealed, one-piece cartridge with a rubber diaphragm and a stainless steel spring and screw. The two units share the load and react instantly as inlet pressure changes. Either one removes in the field with a screw, and units interchange across all PRV 2000 bodies. A built-in indicator shows when the valve has reached its working outlet pressure. The body has male threads at both ends, so it joins female fittings on the header. Non-corrosive plastic and brass parts resist the fertilizers and chemicals carried in irrigation water. A tight diaphragm seal keeps the body from leaking under load.

Supplying Micro Sprinkler Zones and Long Dripline Runs

A firmer preset helps micro sprinklers, spinners and spray stakes reach their full throw and pattern. It also gives pressure compensating drippers and driplines extra margin on long runs or rising ground. This outlet sits inside the 10 to 45 psi working range of Netafim Woodpecker PC drippers. Confirm the rated pressure of the heads or emitters on the zone before settling on this preset. Next, total the zone flow so it lands between 11 and 35 GPM. Sixty micro sprinklers at 30 GPH each, for example, draw 30 GPM. Inlet pressure must equal the outlet setting plus the head loss across the valve at that flow. Netafim publishes head loss curves for each PRV 2000 size to make that check easy. Install the valve after the filter and zone valve, ahead of the submain. Flush the pipe first so grit does not lodge against either diaphragm. Tape the male threads and tighten until the joints stop leaking. After startup, the indicator and a downstream gauge confirm the outlet is holding.
