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, equipped with an adjustable arm, is constructed from durable plastic and brass materials, offering enhanced 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 common plumbing standard, with approximate thread size of 1/2 inch and includes 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 setups, and hydroponic reservoirs. Designed for greater adaptability than conventional metal float valves. Packing Quantity: 2-pack float valves. Engineered to reduce water filling time and minimize maintenance checks. Features a compact float mechanism capable of withstanding higher fluid pressures. Utilizes the buoyancy principle of the float ball to automatically control water inlet flow, maintaining a consistent water level, ensuring adequate water volume, and promoting clean water conditions.
