Adjustable arm: The float valve features an adjustable arm that can be adjusted 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, with adjustable arm, is constructed from high-quality plastic and brass, offering enhanced stability and resistance to rust. Provides reliable water inlet control for consistent performance.Dimensions: The float valve uses 1/2 NPT pipe threads, common in plumbing applications, with thread sizes of approximately 1/2 inch and 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 systems, aquariums, aquaponics, aquaculture, and hydroponic reservoirs. More adaptable than traditional metal float valves.Packing Quantity: 2-pack of water tank float valves. Designed to reduce time spent on water filling and tank monitoring, with effective sealing performance under high pressure. Features a compact float control mechanism capable of withstanding higher fluid pressures.Operational Principle: Utilizes the float ball water level principle to control the water inlet valve, maintaining a consistent water level, ensuring adequate water volume, and promoting clean water conditions.Water Efficiency: Helps reduce water waste in cattle drinking applications by over 30%, contributing to lower wastewater output.Color: As shown in photoMaterial: Plastic and metalPackage Contents:2 x Float valveNote: Light reflection and display differences may cause slight variations between the color of the item in the image and the actual product.
