Adjustable arm: The float valve has an adjustable arm that can be adjusted over 180 degrees to adapt to different water levels. No power source or pump required, hand tight for leak-free operation. High-Quality Material: The mini float valve with adjustable arm is made of high-quality plastic and brass, providing stability and resistance to rust, with reliable water inlet control performance. Dimensions: The float valve uses 1/2 NPT pipe threads, common in plumbing applications, with thread sizes of approximately 1/2 inch and standard washers to prevent leaks. Offers broader applicability compared to traditional metal float valves. Wide range of applications: Suitable for use in ponds, chicken coops, livestock watering tanks, aquariums, aquaponics, aquaculture, and hydroponic reservoirs. More adaptable than traditional metal float valves. Packing quantity: 2-pack of water tank float valves, designed to reduce water filling time and minimize tank maintenance. Features a compact float control mechanism capable of withstanding higher fluid pressures with effective sealing performance. Operates using the float ball water level principle to control water inlet and outlet, maintaining a consistent water level, ensuring sufficient water volume and clean water quality. Helps reduce water waste in cattle watering applications and lowers wastewater discharge.
