• Automatic Water Level Control: The tank float valve operates automatically, adjusting according to the water level of the installed tank or sink. As the water level drops, the float valve mechanism lowers, opening the valve to allow water to flow until the desired level is reached.Ensures water tanks are filled without manual intervention. It greatly reduces our workload. By regulating the flow of water, a tank valve can help conserve water and prevent overflows.
• Rugged and Reliable: The valve body is made of strong nylon resin, which resists corrosion, UV radiation and other forms of damage. Buy once, use for years, and enjoy easy maintenance. This pool auto-fill float valve is ideal for livestock water trough, garden tanks, agricultural irrigation, aquariums, fountains, ponds, swimming pools，and more.
• Water Pressure Range: 1-inch FNPT connection, made of durable ABS plastic. Measures 3-3/4 inches in diameter and 5 inches tall. Maximum pressure: 100 psi. Temperature range: 0 to 150°F. Flow rates from 5 to 40 GPM
• Easy to install: Installation Tutorial ① The 1-inch universal float valve has a 1-inch internal thread for connection. You will need a water pipe with external threads or a mounting bracket. ② Apply plumber's tape to the threads of the hose or mounting bracket, and then screw on the float valve. Hand tighten only. Do not use plumbing compound. ③ Adjust the water source to maximum capacity. ④ Depending on pressure, the valve will close 1 1/2 inches to 2 inches from the bottom of the valve.
• Compact Design: The compact valve uses water pressure to close, eliminating bulky levers and balls. It fits in small spaces and can be stowed away discreetly.
