Set of 10 Mini Barbed Valves 16x16 for Micro Irrigation

Set of 10 Mini Barbed Valves 16x16 for Micro Irrigation (Reference: 2921-10)

These mini barbed valves represent the ideal solution for all your flow control needs in micro irrigation. Specially designed for 16mm tubing, they offer precise and reliable irrigation regulation. Their European manufacture in HDPE guarantees superior quality and exceptional durability in all usage conditions.

Applications and benefits

These 16x16 mini barbed valves are perfectly suited to a multitude of micro irrigation applications. Professional market gardeners use them to regulate watering of their greenhouse crops, allowing precise water dosing according to the specific needs of each variety. Amateur gardeners appreciate their ease of use for watering planters, flower boxes and urban vegetable gardens.

In automated irrigation systems, these valves allow creating independent watering zones, each adjustable according to the specific water requirements of the plantings. Nursery professionals integrate them into their misting circuits to control ambient humidity and targeted watering of young plants. Thanks to their compact format, they integrate discreetly into all types of installations.

Technical specifications and materials

The HDPE (High Density Polyethylene) used for these valves guarantees exceptional resistance to chemicals, UV and thermal variations. This food-grade material ensures perfect safety for watering edible crops. The European manufacture meets the strictest standards for quality and durability.

The 16mm diameter barbs are specially designed to ensure a watertight and durable connection with standard micro irrigation tubing. The ergonomic design of the adjustment wheel allows fine flow adjustment, from complete closure to maximum opening. The robust internal mechanism withstands common service pressures in micro irrigation, up to 4 bars.

The compact design of the valves (optimized dimensions) facilitates their integration in restricted spaces while maintaining excellent handling. The dark color of HDPE limits algae proliferation inside the hydraulic circuit.

Installation and use

Installing these mini barbed valves is of remarkable simplicity. Simply cut the 16mm tubing at the desired location and firmly fit each end onto the valve barbs. Sealing is ensured by the deformation of the tubing on the barb ridges, creating a reliable mechanical connection without requiring hose clamps.

For daily use, the adjustment wheel allows intuitive flow control. Clockwise rotation progressively closes the valve, while reverse rotation opens it. This design allows very fine adjustments, ideal for adapting watering to weather conditions or different plant growth phases.

Maintenance is limited to occasional cleaning of the valve in case of obstruction by particles. Simple disassembly provides access to the internal mechanism for thorough cleaning if necessary. It is recommended to periodically check the condition of the barbs and replace the valve in case of excessive wear.

Expert advice and optimization

To optimize the efficiency of your micro irrigation systems, strategically position these valves at main distribution points. This will allow you to create modular watering zones according to the evolution of your plantings. In series with our Gardena watering timers, they offer complete irrigation automation.

The combination with our self-regulating drippers and micro-sprinklers creates a precision irrigation system. The valves then allow modulating pressure in each secondary circuit, thus optimizing the performance of each type of emitter. This approach guarantees homogeneous water distribution, even on extended installations.

For specialized crops, these valves facilitate adaptation of watering programs according to seasons. During active growth periods, greater opening promotes development, while in maturation phase, flow reduction avoids excess humidity. This modularity directly contributes to improving crop quality and yield.

Professional tip: Mark your valves with labels indicating the served area and optimal settings to facilitate seasonal management of your installations.
