Compact Adjustable Float Valve – Precision Reservoir Level Management

Compact Adjustable Float Valve – Precision Reservoir Level Management

Maintaining a consistent water level is the cornerstone of a stable hydroponic environment. Our Compact Adjustable Float Valve is the professional solution for automating your nutrient reservoir top-ups, ensuring your system never runs dry. Engineered for versatility, this valve features an adjustable arm that allows you to fine-tune the water line with a simple turn of a nut. Whether you are connecting to a gravity-fed header tank or directly to a mains water supply, this float valve provides a reliable, mechanical fail-safe that stabilises your nutrient concentration and protects your pumps from running air.

Best For: Automated nutrient reservoir top-ups, gravity-fed header tank systems, and protecting submersible pumps from running dry in high-evaporation environments.

Key Features

• Precision-Adjustable Float Arm: Features a robust adjustment nut that allows you to alter the angle of the float. This gives you granular control over the final water level without needing to reposition the entire valve body.
• Versatile 13mm Barbed Inlet: Equipped with a standard 13mm barb, making it perfectly compatible with standard Australian low-density poly pipe (LDPE) and irrigation supply lines.
• Mains Pressure Capable: Engineered to handle a variety of pressures, these valves are reliable enough to be connected directly to a mains water supply or a high-capacity backup reservoir.
• High-Impact, Chemical-Resistant Build: Manufactured from premium, horticultural-grade polymers designed to resist the corrosive effects of concentrated mineral salts and pH adjusters.
• Compact 240mm Profile: The streamlined design (approx. 240mm total length) makes it ideal for installation in tight spaces, including smaller nutrient tanks, propagation trays, or auto-pot systems.
• Mechanical Reliability: Operates entirely via gravity and buoyancy, providing a fail-safe automation solution that functions without the need for electronic sensors or external power.

Specifications

• Inlet Connection: 13mm Barbed Fitting
• Total Length: Approx. 240mm (Valve & Float)
• Adjustment Mechanism: Manual Locking Nut (Variable Angle)
• Material: UV-Stabilised, High-Impact Polymer
• Application: Hydroponics, Aquaponics, and Stock Watering Systems

Installation & Maintenance Tips

• Bulkhead Installation: For a professional, leak-proof mount, install the valve through the reservoir wall using a 13mm grommet. Ensure the valve is mounted high enough to allow for your desired maximum water depth.
• The Header Tank Strategy: Connect this valve to a separate 'header' tank filled with plain water or a pre-mixed nutrient solution. As your plants transpire, the float valve will automatically top up the main reservoir, keeping your pH and CF levels more stable between manual changes.
• Debris Protection: If connecting directly to a mains supply or an outdoor tank, we recommend installing an in-line filter before the float valve to prevent grit from interfering with the internal seal.
• Routine Testing: During your weekly reservoir change, manually lift and lower the float to ensure the pivot point remains free of mineral salt build-up and that the valve achieves a total shut-off.

Ideal For (Uses)

• Holiday Automation: Ensuring your indoor grow room stays hydrated for extended periods without manual intervention.
• Commercial Run-to-Waste: Maintaining a constant head of water in mixing tanks to ensure consistent pressure for delivery pumps.
• Evaporation Compensation: Automatically replacing water lost to heat and dry air, preventing nutrient solution from becoming overly concentrated (hot).
