Netafim 3/4in Pressure Regulator 35 psi

Netafim 3/4 Pressure Regulator, 35 psi Preset

Netafim builds this 3/4 inch regulator for irrigation zones that move real volume. It controls flows from 4.5 to 17.5 gallons per minute, or 270 to 1,050 gallons per hour. The outlet is preset at 35 psi and stays there whether the supply sits at 50 psi or spikes much higher. Maximum operating pressure on the inlet side is 145 psi. A single regulating unit inside the body does the work, with an EPDM rubber diaphragm and a stainless steel spring and screw. That unit is sealed in one piece. It swaps out in the field with a screw if the zone ever needs a new preset. Every pressure option has its own unit, so the same body can move to another preset later. A built-in indicator shows when the regulator has reached its proper outlet pressure. One end carries 3/4 inch female threads and the other carries 3/4 inch male threads. Non-corrosive plastic and brass parts tolerate the fertilizers and chemicals that move through most fertigation lines. The diaphragm seals tightly, which keeps the body from leaking under load.

Sizing a High Flow Pressure Regulator for Drip and Sprinkler Zones

Add up the flow of every emitter in the zone before choosing a regulator. A zone of 400 drippers at 2 GPH draws about 13.3 GPM, which falls well inside this unit's range. Required inlet pressure is the outlet setting plus the head loss across the body at that flow. Netafim publishes a head loss chart for each body size so the supply can be checked before installation. Place the regulator downstream of the zone valve and the filter, ahead of the first lateral. The female end accepts a male nipple, while the male end threads into a fitting or adapter. Use thread seal tape on the joints and stop tightening once they seal. This outlet setting suits pressure compensating drippers, micro sprinklers and many overhead sprinkler heads. Check the indicator after startup to confirm the regulator is holding pressure. If the zone flow drops below 4.5 GPM, the low flow body in the same pipe size controls more accurately. Flush new pipe before connecting it, since grit on the diaphragm can disturb the setting. The regulator serves drip and sprinkler systems alike.
