The DHDF21 electromagnetic fountain solenoid valve is designed specifically for controlling water jets in dynamic fountains. Its IP 68 protection rating allows for installation directly inside the water feature, eliminating the need to move it to a dry location. The electromagnetic solenoid valve is a functional and reliable pipeline valve. Its special electromagnetic coils have a service life of up to 1 million activations. The average response time for a membrane solenoid valve ranges from 30 to 500 milliseconds, depending on the diameter, pressure, and design. Electromagnetic valves can be used as remote control shutoff devices or for safety, such 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.
