Adjustable Arm: The float valve features an adjustable arm that rotates over 180 degrees to accommodate varying water levels. No power source or pump required; hand-tightened for leak-free operation. High-Quality Materials: Made from durable plastic and brass, this mini float valve is corrosion-resistant, stable, and provides precise water inlet control. Dimensions: Features 1/2 NPT pipe threads — a standard plumbing thread size (~1/2 inch) compatible with standard washers for reliable sealing. Offers broader compatibility than traditional metal float valves. Wide Application Range: Suitable for ponds, chicken coops, livestock watering tanks, aquariums, aquaponics systems, aquaculture setups, and hydroponic reservoirs. Pack Quantity: Includes 2 float valves. Designed to reduce water-filling time and manual tank checks, with enhanced sealing performance and high-pressure resistance. Uses a compact float mechanism capable of withstanding higher fluid pressure.
