ITEM NAME:1/2 Inch Electric Solenoid Valve DC12/24/220V Solar Coil Valve for Water DC220V Description: The electromagnetic valve has a copper casting structure, which is accurate and reliable, and has the characteristics of wear resistance, corrosion resistance and high temperature resistance. The pressure regulating valve (constant flow valve) functions like a water flow switch. The solenoid valve not only maintains a constant flow constant current, but also prevents dry burn and flow monitoring. The machine has no power consumption and the flow rate is adjustable it has the characteristics of wear resistance, corrosion resistance and high temperature resistance. Applications: High-end water heaters, smart drinking fountains, water heaters, straight drinking machines, water purifiers, steam engines, energy-saving air.The solenoid valve not only maintains a constant flow constant current, but also prevents dry burn and flow monitoring. 1pc Solenoid Valve. The pressure regulating valve (constant flow valve) functions like a water flow switch.
