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 installation ensures leak-free operation. High-Quality Material: This mini float valve is constructed from durable plastic and brass, offering stability and resistance to rust. It 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 washers to prevent leaks. It 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. Offers 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 checks. Features a compact float mechanism capable of withstanding higher fluid pressures while maintaining a secure seal. Operates on the principle of buoyancy, using a floating ball to regulate the water inlet valve, maintaining a consistent water level, ensuring adequate water volume, and helping preserve water quality. Helps reduce water waste in cattle drinking applications by more than 30%, contributing to lower wastewater output.
