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, commonly used in plumbing applications, with approximate thread size of 1/2 inch 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, aquaculture, and hydroponic reservoirs. More versatile 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. Features a compact float mechanism capable of withstanding higher fluid pressures. Operates on the principle of float ball water level control to regulate water inlet flow, 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.
