Netafim 3/4in Pressure Regulator 65psi

Netafim PRV 2000 3/4 Inch, 65 psi Pressure Regulator

Some irrigation zones need pressure, just not the uncontrolled surges a pump or main can deliver. This Netafim PRV 2000 body sets a ceiling of 65 psi, or 4.5 bar, the highest preset in the series. Up to 145 psi, or 10 bar, can enter the inlet, and the outlet still stays at its preset. A single sealed regulating unit does the work, using a rubber diaphragm with a stainless steel spring and screw. If the zone ever calls for a lower setting, the unit swaps out in the field with a screw. Units are interchangeable across every PRV 2000 body, so spares stay simple. Flow through this 3/4 inch body runs from roughly 5.3 to 17.5 gallons per minute. A built-in indicator confirms when the regulator has reached its working outlet pressure. The plastic and brass construction does not corrode and resists the fertilizers and chemicals used in fertigation. The tight diaphragm seal keeps the body from leaking under high load. Response to inlet swings is instant, so a pump cycling on and off does not reach the heads downstream.

Running a Sprinkler Pressure Regulator at the Top Preset

Overhead sprinklers, rotors and misting lines often want more pressure than drip zones to throw water evenly. A preset this high protects those heads and their fittings without starving them. It also limits wear on pipe and solvent joints when supply pressure creeps up overnight. Check the operating range printed by the sprinkler or nozzle maker before choosing this setting. Total the zone flow to make sure it falls inside the rated range of the body. Twelve heads at 1.2 GPM each, for example, draw 14.4 GPM. Inlet pressure has to equal the outlet setting plus the regulator head loss at that flow. Netafim publishes head loss curves for each PRV 2000 size to make that check. Install the regulator downstream of the filter and zone valve, ahead of the first head. Flush new pipe before connecting it so debris does not seat on the diaphragm. Seal the threaded joints with tape and tighten only until they stop leaking. At startup, the indicator and a downstream gauge show the zone holding steady.
