Collection: Water Level Control Valves

U.S. Solid water level control valves are designed to automatically maintain a consistent water level in tanks, cisterns, troughs, and reservoirs. Powered by water pressure alone — no electricity needed — these fully mechanical valves open when the water level drops and shut off when it reaches the preset level. Built for durability and ease of installation, our lineup covers a range of pipe sizes and configurations to suit residential, agricultural, and industrial clean water storage applications.
