The DHA11 solenoid valve is widely used for automatic irrigation in agriculture, garden landscaping, drip irrigation, and other automated control systems. The solenoid valve is a functional and reliable pipeline valve. Its special solenoid coils have a service life of up to 1 million activations. The actuation time of the membrane solenoid valve averages 30 to 500 milliseconds, depending on the diameter, pressure, and design. Solenoid valves can be used as remote control shutoff devices or for safety, as shutoff, switching, or isolating solenoid valves. A normally-open valve operates by maintaining the valve open while static and closing it when voltage is applied to the coil. To maintain the normally-open valve in the closed position, voltage must be applied to the coil continuously.
