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 is constructed with an adjustable arm using high-quality plastic and brass components, 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 approximately 1/2 inch. 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. More adaptable than conventional metal float valves. Packing quantity: 2-pack float valves designed to minimize water filling time and reduce the need for manual tank monitoring. Features a compact float mechanism capable of withstanding higher fluid pressures with effective sealing performance. 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 promoting cleaner water conditions. Helps reduce water waste in cattle watering applications, contributing to lower water consumption and decreased wastewater output.
