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. It offers broader applicability compared to traditional metal float valves. Wide range of applications: Tank float valves are suitable for use in ponds, chicken coops, livestock watering systems, aquariums, aquaponics, aquaculture, and hydroponic reservoirs. They offer greater adaptability than traditional metal float valves. Packing quantity: 2-pack float valves designed to help reduce water filling time and minimize the need for manual tank monitoring. Features a compact float control design capable of withstanding higher fluid pressures while maintaining a secure seal. The float ball operates on a water level float principle to control the water inlet valve, helping maintain a constant water level, ensuring sufficient water volume and improved water quality. Helps reduce water waste in cattle drinking applications, contributing to lower water usage and reduced wastewater discharge.
