Automatic Water Level Control Float Valve Auto Shut Off Tank Filler

Enjoy reliable water management without constantly checking or manually refilling your tank. This automatic water level control valve uses a built-in float mechanism to start water flow as the level drops and stop it once the desired level is restored, with no electricity required. The compact water tank float valve is ideal for tanks, water towers, livestock drinkers, fountains, rain barrels, pools, and other automatic filling applications. Its nylon valve body, stainless steel screws, inlet filter, and compact design provide dependable everyday performance while helping prevent corrosion and debris-related blockage.

Key Features

• Automatic shut off float valve replenishes water when levels fall and automatically stops flow when the float rises to the set level.
• 1/2 inch float valve uses a BSP male-thread connection and can accommodate suitable NPT connections with properly applied PTFE tape.
• Works mechanically without electricity, wiring, sensors, or complicated controls.
• Designed for approximately 10–150 PSI water pressure and operating temperatures of 0–60°C.
• Nylon construction with stainless steel screws helps resist rust, while the included inlet filter helps keep sand and debris away from the float mechanism.
