Adjustable arm: The float valve has an adjustable arm that can be adjusted over 180 degrees to adapt to different water levels. No power source or pump required, hand tight for leak-free operation.<br> High-Quality Material: The mini float valve with adjustable arm is made of high-quality plastic and brass, providing stable performance and resistance to rust. It offers reliable water inlet control for a better user experience.<br> Dimensions: The float valve uses 1/2 NPT pipe threads, common in plumbing applications, with thread sizes of approximately 1/2 inch and standard washers to prevent leaks. It offers broader applicability compared to traditional metal float valves.<br> Wide range of applications: Tank float valves are suitable for ponds, chicken coops, livestock watering, aquariums, aquaponics, aquaculture, and hydroponic reservoirs. They are more adaptable than traditional metal float valves.<br> Packing quantity: 2-pack of water tank float valves, designed to reduce the time needed for water filling and tank monitoring, offering effective sealing under high pressure. Features a compact float control design capable of withstanding higher fluid pressures.<br> The float ball operates on the principle of water level buoyancy to control the water inlet valve, maintaining a consistent water level, ensuring sufficient water volume, and helping keep water clean.<br> Cattle drinking systems using this valve can save over 30% in water usage, reducing wastewater discharge.<br> Color: As shown in picture<br> Material: Plastic + metal<br> Package Contents:<br> 2 x Float valve<br> Note: Light reflection and differences in display screens may cause slight variations in color between the image and the actual item.
