Description
This online button dripper serves as an external emitter for drip irrigation systems in agricultural settings. Constructed from polypropylene (PP) with additives for corrosion resistance, UV protection, and anti-aging properties, it operates across 0.7-3.5 bar. The design features a tool-free removable flag handle, a labyrinth flow channel, and a slanted barb inlet. Three standard flow rates are available with color-coded identification for field recognition.

Product Features
The flag handle allows dripper removal without tools, enabling inspection and cleaning of internal flow paths while the irrigation system remains installed. Maintenance steps include lifting the flag, removing the dripper, cleaning, and reinstalling.
The precision-engineered labyrinth channel creates full turbulent flow during operation. This flow pattern continuously scours internal passages and reduces particle settlement, supporting operation with standard irrigation water quality when paired with proper filtration.
The slanted barb design facilitates insertion into 5/7mm LDPE tubes or directly into punched holes in PE pipes. Once seated, the barb provides retention and creates a seal, requiring minimal installation force.
Three standard flow rates are offered: 4 L/h, 8 L/h, and 16 L/h. Each corresponds to a specific color: black for 4 L/h, blue for 8 L/h, and green for 16 L/h, simplifying identification during installation and maintenance.
Product Uses
These drippers are suitable for orchards (8-16 L/h for mature trees), greenhouses, vineyards, nursery container operations, field row crops, and landscape irrigation. For sloping terrain, they provide stable performance within the recommended pressure range; for significant elevation variations, pressure-compensating models are available.
Select the appropriate flow rate, then connect the dripper to 5/7mm hose or directly into a punched hole in LDPE pipe. Pressurize the system and check for leaks. For cleaning, depressurize the system, remove the dripper via the flag handle, rinse with clean water, and use a soft brush for stubborn debris. Maintain 120 mesh filtration and inspect wetting patterns periodically.
FAQ
A button dripper is an online emitter that attaches externally to irrigation tubing, named for its round, button-like shape. This model includes a flag handle for tool-free removal and cleaning.
Standard flow rates are 4 L/h (black), 8 L/h (blue), and 16 L/h (green). Custom flow rates are available for commercial procurement orders.
A minimum 120 mesh filtration system is required to prevent debris from entering the dripper flow channels.
