Plug&Rain Expert drip pipe 16 mm above and below ground, pressure-compensated SDI 33 cm 2.1 l/h 50 m

50 Meters DVS Drip Line Pro-Line EXPERT | 16 mm | pressure-compensated | Anti-Siphon | 33 cm | 2.1 l/h

The DVS Drip Line EXPERT, featuring the integrated anti-siphon mechanism of the DVS DL-AS emitter, is suitable for both surface and subsurface installation. When the system is switched off, a spring-loaded diaphragm barrier mechanically closes the emitter outlet — soil particles, sand, or mud cannot be sucked in. This eliminates the need for additional air release valves at the highest point of the system. The pressure-compensated DVS DL-AS emitters provide uniform irrigation across the entire length of the drip line — even on slopes and over long runs.

The DVS Drip Line EXPERT is the evolution of classic subsurface drip irrigation: instead of relying on chemical additives or metal elements, a purely mechanical blocking mechanism permanently protects the emitter from contamination — regardless of soil pH, water chemistry, or season. With an effective filtration area of 137.78 mm² — the largest in the class of compact anti-siphon flat emitters — and a particularly thick silicone diaphragm, the DVS Drip Line EXPERT is designed for decades of low-maintenance operation.

Features of the DVS Drip Line EXPERT for the irrigation of flower beds, hedges, and lawn areas:

Install it. Forget it. Done.
The integrated anti-siphon mechanism of the DVS DL-AS emitter provides purely mechanical protection against the suction of soil particles — without chemical additives, without copper elements, and without maintenance requirements. The flat emitter design reduces pressure loss in the line, allows for longer runs, and significantly simplifies installation.

Reliable
The pressure-compensated DVS DL-AS emitters ensure a uniform flow rate over the entire length of the line — with a coefficient of variation (CV) of less than 3% within the operating range of 0.6 to 4.0 bar. Whether it's the first or the last plant on the line: each receives exactly the same amount of water. The effective filtration area of 137.78 mm² with a 580-micron slot width offers maximum tolerance against suspended solids and noticeably extends maintenance intervals for the main filter.

Durable
The brown UV-stabilized PE pipe blends discreetly into planting areas and bark mulch and is designed for permanent surface and subsurface installation. The particularly thick, chemical-resistant silicone diaphragm of the DVS DL-AS emitter maintains its regulatory accuracy even after years of fertilizer exposure — for a system built for longevity from the very start.
