Features No power consumption for efficient water adjustment--- This electric solenoid valve operates without any power consumption, allowing for direct and stable water adjustment. Reliable and durable brass casting structure--- The brass construction of this valve ensures reliability, durability, and resistance to wear, corrosion, and precise water flow control. Function similar to a water flow switch--- This pressure regulating valve, also known as a steady flow valve, functions similarly to a water flow switch, providing consistent water flow and preventing dry burning. Prevents damage and monitors flow--- In addition to maintaining a constant current steady flow, this solenoid valve also prevents dry burning and monitors the flow to ensure optimal performance. Easy installation and maintenance--- With its user-friendly design, this valve is easy to install and maintain, making it convenient for both professionals and DIY enthusiasts.
