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: The 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 common plumbing standard, with approximately 1/2 inch thread size and standard washers to prevent leaks. It offers broader compatibility 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. Offers greater adaptability than conventional metal float valves. Packing quantity: 2 float valves per pack. 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. The float ball operates on a buoyancy principle to control the water inlet valve, maintaining a consistent water level, ensuring adequate water volume, and helping preserve water quality. Helps reduce water waste in cattle watering applications and lowers wastewater discharge.
