1. No power consumption, having direct stability of water adjust.2. Brass brass casting structure is and reliable hard-wearing, anti-corrosion and precise.3. Pressure regulating valve (steady flow valve) function similar to water flow switch.4. This solenoid valve not only can keep the constant current steady flow, but also prevent the dry burning and monitoring the flow.5. Easy to install and maintain.Notice:1.Actual color may be slightly different from the image due to different monitor and light effect2.Please allow 1-3cm deviation due to manual measurementSpecification:Valve Body: BrassThread Size: 1/2"Weight: 212gSize: Approx. 6 * 6.4cm / 2.4 * 2.5inchOperating Altitude: 2500m / 8202ftOperating Temperature: 0 - 40Operating Humidity: ;95% (at 25)Type: Guide (One-way) Rated Voltage: AC 220VOperating Mode: Short-time Quota SystemInsulation Grade: ELiquid: WaterLiquid: Temperature: 0 - 55Water Pressure: 0.02 - 0.8MPaWater Flow Features:Water Pressure (Mpa): 0.02, 0.1, 0.3, 0.8Flow (L/min): ; 5 ; 11 ;18 ; 32Lifespan: ;100,000 Timesincludes:1 x Water Valve
