Micro In-Line Valves & Taps – Precision Flow & Pressure Control Achieving a balanced irrigation system requires granular control over every individual line. Our Micro In-Line Valves provide the ability to fine-tune nutrient delivery to specific pots, zones, or propagation trays. These barbed taps are designed to be installed anywhere along your flexible micro-tubing, offering full on/off functionality and precise adjustment of pressure and flow to individual sprinklers or sprayers. Whether you are dealing with uneven plant growth that requires varying water volumes or simply need to isolate a section of your garden for maintenance, these horticultural-grade valves offer a reliable, leak-proof solution for custom fertigation control. Best For: Controlling individual dripper flow, adjusting micro-sprayer pressure, isolating sections of an irrigation grid, and balancing nutrient delivery across uneven layouts. Key Features Precision Flow Modulation: Features a smooth-operating dial that allows for total shut-off or minute adjustments to water volume, ensuring your plants receive exactly what they need without flooding. High-Tensile Barbed Connection: Engineered with aggressive, well-defined barbs that bite into the flexible tubing for a secure, high-pressure seal that prevents "blow-outs" during pump cycles. In-Line Versatility: Can be installed at any point in your 4mm or 6mm "spaghetti" line network, giving you the flexibility to place control points exactly where they are most accessible. UV-Stabilised Durability: Manufactured from premium, industrial-grade polymers designed to resist the degrading effects of intense HID/LED grow lighting and direct sunlight. Chemical & Salt Resistant: Constructed to handle the continuous flow of concentrated mineral fertilisers and pH adjusters without clogging or corroding internal mechanisms. Opaque Algae Prevention: The deep black pigmentation ensures no light enters the fitting, halting algae growth at the valve junction and protecting your emitters from organic blockages. Available Configurations 4mm Valve (Bag of 50): Specifically designed for 4mm Micro Tube (Spaghetti Tube) and 4mm drip-line systems. 6mm Valve (Bag of 25): High-flow micro-valves for 6mm tubing, ideal for high-volume drippers and Hydro Halo setups. Specifications Fitting Type: In-Line Barbed Tap Mechanism: Manual Twist-Dial Valve Compatibility: Flexible Micro-Tubing only (not for use with rigid risers) Material: High-Impact Polypropylene / ABS Colour: Black (Light-Proof) Installation & Maintenance Tips Soft-Seal Technique: If you find the micro-tubing difficult to push onto the valve barbs, dip the end of the tubing in warm water for 5 seconds. This softens the plastic, allowing the valve to slide on effortlessly for a tighter seal as it cools. Pressure Balancing: Use these valves to restrict flow to plants closest to your pump. By slightly closing the valves on the "near" plants, you force more pressure to the "far" plants, ensuring a uniform drip rate across the entire system. Routine Testing: Periodically turn the valves fully off and on to ensure the internal mechanism remains free of mineral salt build-up, especially when using heavy organic or salt-based nutrients. Ideal For (Uses) Isolating Unused Sites: Easily shut off water to empty pots or propagation zones without having to re-plumb your entire manifold. Sprayer Adjustment: Fine-tuning the spray radius of micro-jets to ensure water stays within the pot and doesn't wastefully saturate the grow room floor. Custom Manifolds: Creating professional-grade control boards where each feeder line can be manually adjusted for maximum precision.
