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: 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, commonly used in plumbing applications, with standard washers to prevent leaks. Thread size is approximately 1/2 inch. 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, aquaculture, and hydroponic reservoirs. More adaptable 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 with effective sealing. Operates using the buoyancy principle of the float ball to control water inflow, maintaining a consistent water level, ensuring adequate water volume and improved water quality. Helps reduce cattle drinking water waste by over 30%, contributing to lower wastewater output.
