Adjustable arm: The float valve features an adjustable arm that can be adjusted over 180 degrees to accommodate various water levels. No power source or pump required; hand-tight design ensures leak-free operation. High-Quality Material: The mini float valve with adjustable arm is constructed from high-quality plastic and brass, providing enhanced stability and resistance to rust. It offers reliable water inlet control for consistent performance. Dimensions: The float valve uses 1/2 NPT pipe threads, commonly used in plumbing applications, with approximate thread size of 1/2 inch and standard washers to prevent leaks. Offers broader applicability compared to traditional metal float valves. Wide Range of Applications: Suitable for use in ponds, chicken coops, livestock watering tanks, aquariums, aquaponics systems, aquaculture, and hydroponic reservoirs. Designed for greater adaptability than conventional metal float valves. Packing Quantity: Includes 2 float valves. Engineered to minimize water filling time and reduce the need for manual tank monitoring. Features a compact float control mechanism capable of withstanding higher fluid pressures while maintaining a secure seal. Operates on the principle of float ball buoyancy to automatically control water inlet and outlet, maintaining a consistent water level, ensuring adequate water volume, and promoting clean water conditions. Helps reduce cattle drinking water waste by over 30%, contributing to lower wastewater output.
