Netafim 2in Series 80 Globe Control Valve 24VAC

Netafim 2 Inch Series 80 Globe Control Valve for Large Zones

Big irrigation zones need a valve that can move high flow without eating pressure, then shut off cleanly when the cycle ends. Netafim's Series 80 nylon valve in 2 inch globe form, model 61ET2GH2 and item 71640-007660, is built for that job. Netafim recommends it for flows from 0.25 to 176 GPM, a wide span that comes from very low friction loss through the body. Operating pressure runs from 7 psi up to 150 psi, and water can be as warm as 140°F. The body, bonnet and diaphragm seat are glass reinforced polyamide, with stainless steel hardware and spring. That build resists corrosion and handles water with mild acidity or corrosive content. A fully supported diaphragm gives a tight seal, while the quick reaction suits short mist pulses. An integrated check valve keeps the valve closed until the controller calls for it to open. A clog-free labyrinth inlet feeds the command water, so the valve copes with dirty water and reclaimed sources. The flow control stem lets a grower throttle the zone by hand, from fully closed to full capacity.

Wiring and Setting Up a 24VAC Solenoid Valve

The standard solenoid runs on 24VAC within plus or minus 10 percent. Inrush current is 0.22 A and holding current is 0.095 A, which Netafim notes allows long wire runs from valve to controller. The solenoid has no diode and is stable against voltage swings, with low sensitivity to dirt. Netafim lists the 2-way valves as optimal for vertical installation. The globe body measures 6 9/16 by 6 1/2 by 6 5/8 inches and weighs about 2 lb. Install a filter upstream so debris does not reach the diaphragm or the command circuit. Size the zone so its flow sits comfortably inside the recommended range rather than at either extreme. Use the flow control stem to trim a zone that runs higher pressure than its emitters want. The valve works for remote control, master valve duty and automated or manual operation. Netafim lists greenhouse and nursery irrigation, hydroponic systems and mist systems among its applications.
