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. It offers reliable water inlet control for a better user experience. 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. It offers broader applicability compared to traditional metal float valves. Wide range of applications: Tank float valves are suitable for ponds, chicken coops, livestock watering, aquariums, aquaponics, aquaculture, and hydroponic reservoirs. They offer greater adaptability than traditional metal float valves. Packing quantity: 2-pack of water tank float valves, designed to reduce water filling time and minimize the need for manual tank checks. Features a compact float control mechanism capable of withstanding higher fluid pressures while ensuring a secure seal. The float ball operates on the water level floating principle to control the water inlet valve, maintaining a consistent water level, keeping water volume sufficient, and helping maintain clean water conditions. Cattle drinking water usage is reduced by more than 30%, contributing to lower wastewater discharge.
