Size flexibility You can connect the float valve to a 1/2inch water supply pipe and install the appropriate number of float valves according to the water tank size to meet different needs. materials The float valve ball is made of PE, and other parts are ABS. They are resistant to low temperatures and corrosion, providing longterm service. Automatic filling and stopping The float valve features an adjustable arm. When the water level is low, the valve gate opens to let water in. As the level rises, the ball float valve and the adjustable arm form a flat angle to close, achieving automatic adjustment of water levels. Userfriendly operation The valve ball angle is adjustable with an arm, allowing flexible settings based on water level requirements. The water level is automatically controlled without power supply or a pump. Key benefits Automatic water level control without electricity or a pump, reducing monitoring and risk of overflow. Flexible configuration for different tank sizes by adjusting the number of valves. Durable, coldresistant and corrosionresistant materials for reliable, longterm use. Simple, adjustable operation to suit varying water level needs. Specifications and compatibility Connection: 1/2inch water supply pipe Configuration: install the appropriate number of float valves according to water tank size Materials: PE ball, ABS components Performance: automatic filling and stopping based on water level, no external power required Usage scenarios Farm water troughs and poultry drinking tanks: use multiple valves for large tanks to maintain steady water levels automatically. Home rainwater harvesting and garden irrigation tanks: keep reservoir levels stable without electricity, supporting lowmaintenance operation. Outdoor storage or greenhouse tanks in cold climates: reliable fillstop control with materials designed for low temperatures and corrosion resistance.
