DIG PCA Online Pressure Compensating Drip Emitter with Check Valve - Pack of 300 – 0.3 GPH

The innovative PCA-CV pressure compensating drip emitter with a check valve has a water-saving feature that eliminates water drainage when the system is shut off and is designed to produce a consistent flow rate over a wide range of pressures in challenging terrain or complicated layouts. The drip emitter’s self-activated flushing mechanism provides excellent clog resistance for use in a wide range of applications in residential and commercial landscapes, greenhouses, and nurseries. Features Drip emitter’s built-in check valve eliminates water draining when the system is shut off Ideal solution for long laterals, pulse irrigation, light soil and for greenhouse applications Ideal for watering plants in pots and containers Pressure compensating feature with built-in non-drain mechanism gives consistent flow and reduces lateral filling time, supporting water savings Design of drip emitter‘s self-activated flushing mechanism ensures continuous flushing of sediments and small particles for better operation over time Built-in non-drain feature eliminates the draining of water from the laterals when the system is shut off Colored barbed cap outlet enables easy identification of dripper flow rate Barbed outlet can be configured to work with 1/8” or 1/4” micro tubing for branching from the dripper For irrigation of home gardens, commercial landscapes, greenhouses, nurseries, orchards, deciduous plants and trees Outstanding flow regulation and consistent flow over a wide range of pressures Composed of superior materials for a long life.
