PCA-CV PC Drip Emitter with Built-in Check Valve

The innovative PCA-CV pressure compensating drip emitter with check valve support a water saving feature which eliminate water drainage when the system is shut off is designed to produce a consistent flow rate over a wide range of pressures in challenging terrain or complicated layouts. The PCA-CV pressure compensating 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.



  • The drip emitter’s built-in check valve feature 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 
  • The pressure compensating feature with the built-in non drain mechanism gives consistent flow and reduces lateral filling time, supporting water savings 
  • The design of drip emitter‘s self-activated flushing mechanism ensures continuous flushing of sediments and small particles for better operation over time
  • The 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
  • The barb outlet can be configured to work with 1/8” or ¼” micro tubing for branching from the dripper 
  • For irrigation of home gardens, commercial landscapes, greenhouses, nurseries, orchards, deciduous plants, and trees
