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 installation ensures leak-free operation. High-Quality Material: The mini float valve with adjustable arm is made of plastic and brass, providing stable performance and resistance to corrosion. It offers reliable water inlet control. 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. Wide range of applications: Tank float valves are suitable for ponds, chicken coops, livestock watering, aquariums, aquaponics, aquaculture, and hydroponic reservoirs. Packing quantity: 2-pack of water tank float valves, featuring a compact float control design capable of withstanding higher fluid pressures. The float ball operates on the principle of water level buoyancy to control the water inlet valve, maintaining a consistent water level and ensuring sufficient water volume.
