Three-Way Brass Solenoid Valve with Self-Clean Filter & Manual Drain

1/2 Inch 3-Way Brass Solenoid Valve with Built-In Filter & Manual Slag Discharge Ball Valve, Waterproof Pure Copper Coil Electric Manual Integrated Solenoid Valve for Agricultural Irrigation Water Sprayer Equipment Upgraded 3-Way Electric Manual Integrated Brass Solenoid Valve with Self-Clean Slag Discharge Filter Designed specifically for agricultural irrigation, mist spraying and general water control systems, this all-in-one brass solenoid valve solves two major pain points of traditional valves: frequent clogging from sediment and complete shutdown risk during power failures. It combines automatic electric control, manual emergency bypass, built-in debris filtration and slag discharge into one compact unit for reliable long-term water flow management.  1 – 100% Waterproof Pure Copper Coil The valve is fitted with a heavy-duty full pure copper electromagnetic coil with sealed waterproof casing. Fast, lag-free response pilot head delivers instant open/close action without sticking or freezing Wide working pressure range: 0kg/cm² to 10kg/cm², stable performance under variable water pressure Low heat generation, high power efficiency, anti-aging design for years of continuous operation Insulated wiring prevents short circuits in damp outdoor irrigation environments  2 – Built-In Three-Way Self-Contained Filter & Manual Slag Drain The integrated Y-type filter with stainless steel mesh traps sand, rust flakes and plant debris before they enter the valve core to block flow. The attached red-handle ball drain valve lets you quickly flush accumulated sediment without disassembling the whole system, drastically cutting maintenance time and extending the valve’s service life. No more frequent valve disassembly to clear clogs. 3 – Dual Electric & Manual Integrated Control Dual-mode operation eliminates downtime risks: Automatic electric mode: Connect wiring to your irrigation controller for scheduled auto water on/off Manual emergency mode: Flip the red spray valve handle to manually open or shut off water instantly during power outages, controller faults or maintenance work  4 – Solid Anti-Corrosion Brass Valve Body The entire valve main body is cast from thick high-quality brass: Excellent rust and oxidation resistance for outdoor, damp farm/garden use Smooth internal water channels reduce flow resistance Precision machined thread ports for leak-free connection High pressure resistance, no cracking or deformation under regular irrigation pressure
