Adjustable arm: The float valve features an adjustable arm that can be set 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 is constructed from durable plastic and brass, offering stability, rust resistance, and reliable water inlet control for consistent performance. Dimensions: Features 1/2 NPT pipe threads, commonly used in plumbing applications, with approximately 1/2 inch thread size and standard washers to prevent leaks. Offers broader compatibility 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. Provides greater adaptability than conventional metal float valves. Packing quantity: Includes 2 float valves. Designed to minimize water filling time and reduce the need for manual tank monitoring, with effective sealing performance under high pressure. Compact float mechanism withstands higher fluid pressures. Operates using the float ball principle to automatically control water inlet flow, 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.
