Contains 2 pieces of 1/2 inch float valves, each equipped with 1 filter and 1 plastic water outlet. High-quality material: The water float valve is made of polyamide, an environmentally safe material with good mechanical strength, rigidity, hardness, and aging resistance. Offers long service life, low failure rate, and helps conserve water resources. Features: Compact design allows use in small water tanks. Non-metallic construction prevents rust. Provides higher water flow compared to standard models (estimated flow rate up to 40 gallons per minute at 60 psi), allowing faster tank filling. Easy to install: Insert the valve into the water inlet following the direction marked on the valve body, then connect the ball valve to the water pipe. Note that the filter side is the water inletdo not install in reverse. When installing multiple valves, align the bottoms at the same height to ensure consistent operation. Clean any impurities from the pipe before use.
