Adjustable arm: The float valve features an adjustable arm that can be positioned 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 with adjustable arm is constructed from durable plastic and brass, offering stability, corrosion resistance, and reliable water inlet control for consistent performance. Dimensions: The float valve uses 1/2 NPT pipe threads, commonly used in plumbing applications, with approximately 1/2 inch thread size 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 systems, aquaculture, and hydroponic reservoirs. Provides greater adaptability than standard metal float valves. Packing quantity: 2-pack of water tank float valves. Designed to minimize water filling time and reduce maintenance. Features a compact float mechanism capable of withstanding higher fluid pressures. Utilizes the float ball principle to automatically control water inlet flow, maintaining a consistent water level, ensuring adequate water volume, and promoting clean water conditions. Helps reduce water waste and lowers discharge pressure. Color: As shown in photo. Material: Plastic and metal. Package contents: 2 x Float valve.
