Unrivaled Performance: A Deep Dive into Netafim's Core Technologies

The superior performance of Techline CV XR is the result of four interconnected technologies working in concert to create a dripline that actively protects itself from the primary causes of system failure.

The XR Advantage: Permanent, Chemical-Free Root Defense

Subsurface Drip Irrigation (SDI) offers tremendous water-saving benefits, but its greatest vulnerability has always been root intrusion—the single biggest cause of system failure. The Techline CV XR solves this problem permanently with its revolutionary dual-layer defense system. First, each emitter features a patented physical root barrier with an offset flow path and raised outlet that makes it difficult for roots to penetrate.

Second, and most critically, is the XR (eXtra Resistant) technology. Through a proprietary process, Cupron copper oxide is infused directly into the material of the emitter itself. Unlike competing products that rely on slow-release chemical herbicides or separate copper chips that can deplete over time, Netafim's infused copper oxide is a non-migrating, non-leaching component of the dripper that lasts for the entire life of the product. This creates a permanent, chemical-free zone around the emitter that safely deters root growth without harming the plant. This unmatched reliability is backed by Netafim's 17-year warranty against emitter plugging from root intrusion, transforming your irrigation system from a temporary setup into a long-term infrastructure investment and providing absolute peace of mind.

Precision on Any Terrain: Check Valve (CV) and Pressure Compensation (PC)

Achieving uniform water distribution is a challenge in any landscape, especially those with varying elevations or long lateral runs. The Techline CV XR masterfully solves this with the seamless integration of Pressure Compensation (PC) and a Check Valve (CV). The PC technology ensures that every emitter along the line delivers a precise and equal amount of water, regardless of its position or variations in system pressure within the specified range of 14.5 to 58 PSI. This means the last plant on a 250-foot run receives the exact same hydration as the first.

The Check Valve (CV) addresses the distinct challenge of elevation. In standard systems on slopes, water drains out of the lowest emitters after shutdown, causing oversaturation at the bottom and dry conditions at the top. Each Techline CV XR emitter contains a check valve that closes at 2 PSI, holding back up to 4.6 feet of water elevation within the dripline. This keeps the entire system fully charged with water at all times. The result is perfect synchronization: upon startup, every emitter begins watering instantly and uniformly, eliminating drainage, preventing erosion, and ensuring every part of the landscape receives precisely the water it needs. For contractors, this technological synergy simplifies system design, often reducing the need for multiple zones and valves on complex sites, which translates directly to labor and material savings.

The Unseen Guardian: Anti-Siphon and Continuous Self-Flushing

For driplines buried underground, the greatest threats after roots are dirt and debris. The Techline CV XR employs a multi-layered active defense system to ensure a lifetime of clog-free operation. When an irrigation system shuts down, the resulting vacuum can suck surrounding soil and contaminated water back into the emitters, a primary cause of clogging in subsurface applications. The Techline CV XR's anti-siphon mechanism prevents this "suck-back," sealing the emitter outlet and acting as a one-way gate to protect the system's integrity.

As a second layer of defense, the dripline features a continuous self-flushing design. Unlike systems that only flush at the beginning or end of a cycle, the Techline CV XR's emitters flush debris as it is detected throughout the entire watering operation. This process is enhanced by Netafim's patented TurboNet™ labyrinth, which features an extra-wide flow path that allows contaminants to pass easily through the dripper instead of accumulating. This redundant, self-healing system works tirelessly underground to protect your investment, ensuring consistent flow and eliminating the need for costly and disruptive repairs.

Versatile Applications for Any Project

The robust, multi-functional design of the Netafim Techline CV XR makes it the ideal choice for a vast range of demanding applications:

• Residential Landscapes: Perfect for subsurface installation under lawns (turfgrass), in flower beds, vegetable gardens, and around shrubs and trees.
• Commercial and Public Spaces: The durable, vandalism-resistant choice for sports fields, golf courses, municipal parks, and high-traffic commercial properties.
• Challenging Terrains: Unmatched performance on steep slopes, berms, and irregularly shaped or narrow planting areas where wind and runoff are concerns.
• Architectural and Green Building: The premier solution for innovative projects such as green roofs, living walls, and raised planters. Its use of recycled materials qualifies for LEED credits.

Professional-Grade Technical Specifications

Installation and Compatibility

For optimal performance, connect using standard 17mm insert fittings. A minimum of 120 mesh filtration is required upstream to protect the system. For subsurface turfgrass applications, a burial depth of 4 to 6 inches is recommended. To prevent damage to the buried dripline, avoid deep mechanical aeration or cultivation directly over the tubing lines. On sloped terrain, laterals should be run perpendicular to the slope (across the contour) whenever possible to maximize water distribution efficiency.
