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 consistent 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 help 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 systems, aquaculture, and hydroponic reservoirs. More adaptable than traditional metal float valves. Packing quantity: 2-pack 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 maintaining a secure seal. The float ball operates on a water level buoyancy principle to control the water inlet valve, helping maintain a constant water level, ensuring sufficient water volume and improved water cleanliness. Helps reduce water waste in cattle watering applications, contributing to lower water consumption and reduced wastewater discharge.
