Adjustable arm: The float valve features an adjustable arm that can be positioned over 180 degrees to accommodate various water levels. No power source or pump required; hand-tight design ensures leak-free operation. High-Quality Material: This mini float valve, equipped with an adjustable arm, is constructed from durable plastic and brass materials. It offers enhanced stability, resists rust, and provides reliable water inlet control for consistent performance. Dimensions: The float valve uses 1/2 NPT pipe threads, a standard in plumbing applications, with approximately 1/2 inch thread size and compatible with 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 setups, 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, offering effective sealing performance under high pressure. Features a compact float mechanism capable of withstanding higher fluid pressures. Operates on the principle of buoyancy using a float ball to automatically control the water inlet valve, 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.
