the Woodpecker Pressure Compensating Junior with the CNL feature. Perfect for vineyards, orchards and greenhouse or nursery applications because of its uniform flow rate over a wide range of pressures. The patented pressure differential system provides uniform flow rate over a wide range of operating pressures ensuring precise water distribution. The continuous self-flushing design greatly reduces clogging. The CNL feature is an internal check valve or non-draining mechanism that eliminates refill and drainage effects.

Features: 

• Recommended Operating Pressure Range: 10.2 – 45 psi
• Shut-Off (Closing) Pressure: 1.7 PSI
• Recommended Filtration: 120 Mesh minimum
• Available in several flow rate options to meet all your needs
• Inlet: 1/4" barb
• Outlet: 1/8" barb

Please Note: The CNL (closed no leak or check non leak) feature means the dripper will open at a specific pressure once the line fills with water and then close at a specific pressure when the system shuts down. This design is not recommended in a low pressure gravity feed drip system. There is not sufficient consistent pressure to operate properly.
