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.\u003c\/p\u003e\n  \n  \u003chr\u003e\n  \n  \u003cp\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e Controlling individual dripper flow, adjusting micro-sprayer pressure, isolating sections of an irrigation grid, and balancing nutrient delivery across uneven layouts.\u003c\/p\u003e\n  \n  \u003ch3\u003eKey Features\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePrecision Flow Modulation:\u003c\/strong\u003e 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.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHigh-Tensile Barbed Connection:\u003c\/strong\u003e 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.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIn-Line Versatility:\u003c\/strong\u003e 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.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eUV-Stabilised Durability:\u003c\/strong\u003e Manufactured from premium, industrial-grade polymers designed to resist the degrading effects of intense HID\/LED grow lighting and direct sunlight.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eChemical \u0026amp; Salt Resistant:\u003c\/strong\u003e Constructed to handle the continuous flow of concentrated mineral fertilisers and pH adjusters without clogging or corroding internal mechanisms.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOpaque Algae Prevention:\u003c\/strong\u003e The deep black pigmentation ensures no light enters the fitting, halting algae growth at the valve junction and protecting your emitters from organic blockages.\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \n  \u003ch3\u003eAvailable Configurations\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003e4mm Valve (Bag of 50):\u003c\/strong\u003e Specifically designed for 4mm Micro Tube (Spaghetti Tube) and 4mm drip-line systems.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003e6mm Valve (Bag of 25):\u003c\/strong\u003e High-flow micro-valves for 6mm tubing, ideal for high-volume drippers and Hydro Halo setups.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eSpecifications\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFitting Type:\u003c\/strong\u003e In-Line Barbed Tap\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMechanism:\u003c\/strong\u003e Manual Twist-Dial Valve\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Flexible Micro-Tubing only (not for use with rigid risers)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-Impact Polypropylene \/ ABS\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e Black (Light-Proof)\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eInstallation \u0026amp; Maintenance Tips\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSoft-Seal Technique:\u003c\/strong\u003e 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.
