Uniform flow rate
Raised barbed outlet prevents water runoff along the drip lateral
DIG's W22 Button Drip Emitters utilize a unique labyrinth flow path design producing a turbulent flow, ensuring years of consistent operation with less chance of clogging. The Button Drip Emitters are available in flow rates of .5, 1, or 2 GPH, operate at 15 to 25 PSI, and are non-pressure compensating; the flow rate depends on the incoming inlet pressure. The nominal pressure for the Button Drip Emitter is 15 PSI. With higher pressure, the drip emitter will allow more flow, and with lower pressure, less flow will occur. The Button Drip Emitters are available in packs of 5, 25, 50, and 100, all with 1/4 in. barbed inlet and small nipple outlet. Recommended for residential and commercial applications, the W22 Button Drip Emitter is a low cost solution, ideal to use in systems with shorter runs, systems on level terrain, or low pressure gravity feed drip systems.
