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: This mini float valve, equipped with an adjustable arm, is constructed from durable plastic and brass materials. It offers stable performance, resists rust, and provides reliable water inlet control for consistent operation. Dimensions: The float valve uses 1/2 NPT pipe threads, a standard in plumbing applications, with approximately 1/2 inch thread size and compatible washers to prevent leaks. Its design 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. Offers greater adaptability 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, providing effective sealing performance under high pressure. Features a compact float mechanism capable of withstanding higher fluid pressures. Functionality: Operates based on the float ball's water level detection principle to automatically control the water inlet valve, maintaining a consistent water level, ensuring adequate water supply, and helping preserve water quality. Water Efficiency: Helps reduce water waste in cattle drinking systems by more than 30%, contributing to lower wastewater output.
