The 180° and the 360° adjustable flow drip emitters have a flow range of 0 to 10 GPH at a preset pressure of 25 PSI. When the cap is rotated the adjustable drip emitter flow and the radius of the soaked area change from a drip to a gentle stream pattern to off. This feature allows the user to adjust the flow to each individual plant as needed. Twisting the dial on the drip emitter towards the "+" or the "-" signs allows the user to increase or decrease the flow rate. Our range of adjustable drip emitters come with 5" spike and 1/4" side barb inlet or with 1/4" barb inlet only. The ideal use for this range of adjustable drip emitters is for a group of plants or under a large individual plant.
When using this type of drip emitter be aware that as you adjust the flow, the total flow rate of the system may be affected and this may lower the system uniformity. In other words, increasing the flow from each adjustable drip emitter on your system may limit the efficiency of the system. For example, on 1/4" micro tubing only three to four adjustable drip emitters should be used when they are opened to the maximum flow, and it is recommended to use no more than 20 to 25 adjustable drip emitters on 1/2" drip tubing.
