Excel™ PCD CV 17 mm Dripline with Check Valve

DIG’s Excel™ PCD CV Pressure Compensating Dual Outlet Dripline with Check Valve is a reliable, durable, and precise solution for subsurface irrigation, particularly suited for narrow or dense plantings. This advanced dripline features cylindrical drip emitters with built-in check valves that prevent siphoning when water pressure drops below 2.5 PSI. This anti-siphoning capability protects the emitters from sediment, soil particles, and debris entering the dripline, ensuring long-term reliability.

Each emitter is equipped with a floating diaphragm that regulates and maintains a consistent flow rate across a wide range of inlet pressures, from 12 to 50 PSI, making it ideal for demanding conditions. The Excel PCD CV Dripline also includes a colored stripe to indicate flow rate, simplifying identification and installation.

Unlike traditional driplines with a single outlet, the Excel PCD CV Dripline is designed with two outlets per emitter. This dual-outlet design provides redundancy; if one outlet becomes blocked, the opposing outlet continues to function, maintaining consistent performance.

Constructed from premium low-density polyethylene resins with UV protection, the dripline combines robust environmental stress-cracking resistance and burst strength with its anti-siphoning capability, making it an ideal choice for subsurface irrigation applications. The durable, large cylindrical emitters ensure the system’s reliability and efficiency in various challenging environments.

Features:

• Versatile Installation: Can be installed both above or below grade, offering flexibility in a variety of applications.
• Built-In Check Valves: Inline emitter check valves prevent drainage when water pressure drops below 2.5 PSI, safeguarding the emitters from siphoning small sediment and soil particles into the dripline.
• Dual Outlet Design: Each emitter features two outlets; if one becomes blocked, the second outlet on the opposite side ensures continued performance and reliability.
• Customizable Options: Available in two flow rates, with a wide range of emitter spacing and tubing lengths, allowing for maximum design flexibility to suit diverse irrigation needs.
• Color-Coded Identification: Dripline comes with double-striped color codes, representing different flow rates for easy identification.
• Pressure Compensating: Provides consistent flow uniformity across varying operating pressures and line lengths, ensuring efficient water distribution.
• Integrated Emitter Design: The drip emitter and diaphragm are self-contained units, molded directly into the interior wall of the tubing for enhanced durability and performance.
• Clog-Resistant Flow Path: The flow path design is optimized to resist clogging, with turbulent flow through large labyrinth water passages leading water into the flow control chamber.
• Self-Flushing Diaphragm: The floating silicone diaphragm within the flow control chamber regulates constant flow rates and allows for self-flushing, clearing debris that might bypass the inlet filter.
• Secondary Filtration: The intake inlet is equipped with raised grooves acting as a secondary filter, continuously flushing particles away from the labyrinth to enhance clogging resistance.
• Root and Debris Protection: The check valve, combined with dual oppositely oriented outlets, acts as a physical barrier against root intrusion and debris, maintaining system integrity.
• Chemical and UV Resistance: Resistant to the chemicals and fertilizers commonly used in landscaping and protected against UV degradation for long-lasting durability.
• Flexible and Easy to Install: The flexible tubing design facilitates easy installation, adapting to various layouts and environments.
• Clear Labeling: The dripline is printed with flow rate and size for easy identification during installation.
• Wide Compatibility: Designed for use with DIG’s 17 mm barb fittings, .670″ OD compression fittings, and universal NUTLOC™ fittings, ensuring compatibility with existing systems.
