Netafim SpinNet Red Mist, Red Body, Green Spinner with Check Valve - 25 Pack

Netafim SpinNet Check Valve Sprinkler, Red/Red/Green Large, uniform watering strips come from many light heads working together across the house. This bag holds 25 SpinNet heads, Netafim item 64200-010805, model 03551200070GL-B, in the R-R-GN configuration. Red mist control and red body sit over a green spinner, and each head arrives with its check valve fitted. Average flow is 18.4 GPH at 32 psi. The green rotor gives a high trajectory, spreading water about 25 ft across from 1.5 m up at 36 psi. Long reach at a moderate flow lays water down gently over a wide strip. Between cycles the check valve holds water in the line, so nothing drains onto the crop. When the zone opens, every head on the line starts at once instead of waiting for the pipe to refill. The spinner runs without a bridge over it, so the head itself has no drip point. Heads hang below the supply pipe, and a vibration action keeps minerals from collecting in the nozzle. Laying Out Greenhouse Sprinklers for Wide Bays At 3 ft spacing, one R-R-GN line waters an 18 ft bay with the heads 2 to 3 ft above the crop. Raise the line to 4 or 5 ft above the crop and it covers 20 to 22 ft bays. Two lines 17 to 19 ft apart handle 32 to 36 ft bays at 3 ft above the crop. Hanging assemblies with 12 to 48 in drops set the head height from PE supply tubing. A 125 ft line of these heads draws about 13 GPM, so size the zone valve and filter to match. Use 1 in polyethylene supply pipe on runs of 100 ft or longer. A 35 psi regulator typically delivers the right average head pressure after line losses. Keep heads in the 29 to 43 psi range, with 120 mesh filtration ahead of the zone. Flush the mainline and every supply pipe before attaching heads, since the check valves can trap debris. Heads come apart by hand for cleaning and accept acid treatment and standard agrochemicals.
