Key benefits Automatic water level control: The float ball valve with 1/2 inch thread (DN15) automatically shuts off water flow when the tank reaches the desired level, preventing overflow and keeping a steady water level in tanks, cisterns, and storage systems. flow efficiency design: ABS plastic body with EPDM sealing components delivers strong water flow capacity while maintaining reliable sealing. It operates effectively within a water pressure range of 0.02 to 1.0 MPa for dependable automatic filling. Temperature resistant construction: Designed to withstand harsh conditions from 30 C to 70 C, suitable for a range of water applications including corrosive media and weak acid environments. The PE floating ball remains buoyant and responsive. Quick installation setup: Compact 15 cm overall length enables easy installation in tight spaces, with a flexible threading system that connects securely to standard plumbing fittings without specialized tools or extensive modifications. Specifications and attributes Thread size: 1/2 inch (DN15) Overall length: approximately 15 cm Body material: ABS plastic Seals: EPDM Floating ball material: PE Operating pressure: 0.02–1.0 MPa Temperature range: 30 C to 70 C Compatible applications: tanks, cisterns, and storage systems; suitable for use with corrosive media and weak acid environments Applications and use scenarios Domestic water storage or toilet cisterns: Keeps the water level steady during filling and use, preventing overflow and reducing manual monitoring. Rainwater harvesting or irrigation tanks: Maintains automatic filling and consistent water levels in outdoor reservoirs or farm irrigation systems. Industrial or chemical storage: Suitable for tanks handling mildly corrosive media or weak acids, where reliable automatic fill control is needed in challenging environments. Tightspace installations: The compact 15 cm length and flexible threading allow secure connection to standard fittings in constrained areas without extensive modifications.
