DC 4.5V 1/2 inch brass electric solenoid valve with a pulse electromagnetic controller for automatic water control. Key benefits - Automates toilet flushing: acts as an automatic sensor flush valve switch, delivering convenient and reliable water control when needed. - Durable brass construction: built for long-term use in varied water systems with corrosion resistance and reliable sealing. - Low energy operation: powered by DC 4.5V, delivering efficient performance with relatively low energy consumption. - Precise control: pulse electromagnetic controller provides accurate, timely valve actuation for proper flushing performance. - Compact and compatible: 1/2 inch connection size fits standard plumbing layouts and quick retrofits. Specifications to note - Function: solenoid valve with pulse electromagnetic controller for automatic water control - Material: brass - Connection size: 1/2 inch - Power supply: DC 4.5V - Application: designed for toilet use as an automatic sensor flush valve switch What makes it stand out - Combines a brass body with a pulse control system for smooth and repeatable water flow - Low voltage operation reduces wiring complexity and energy use - Suitable for toilets and other water control applications that require automatic, sensor-driven actuation Use scenarios - Scenario 1: Automatic sensor flush system in a residential or commercial toilet, providing hands-free operation with reliable flushing performance. - Scenario 2: Retrofit or new installation in public restrooms where low-voltage, compact valves are preferred for safe and maintenance-friendly operation. - Scenario 3: Small-scale water control projects that need a compact 1/2 inch valve with precise timing and automatic actuation, such as limited plumbing modifications or sensor-based systems. This valve maintains its core features and performance: a brass, 1/2 inch solenoid valve driven by a DC 4.5V supply, with a pulse electromagnetic controller to ensure precise, timely water flow for proper toilet flushing.
