DN20 Solenoid Valve - Normally Open / Normally Closed

As Makers, we enjoy tinkering with all types of electronics and mechanical contraptions to improve our lives. DN20 Solenoid Valves are handy components that allow you to build your own water flow control system. Makers interested in home garden systems, fisheries and other water projects will love the chance to make the ordinary task of watering into an automatic feature. We stock a variety of Solenoid Valves and Water Flow Sensors for Makers to find the right fit in their projects.

These DN20 Solenoid Valves are made for pipes with internal diameters of 20mm and have clever design that integrates electro valves with an inbuilt DC motor. Large torque, low noise and easy-to-install, the DN20 Solenoid Valve opens opportunity for IoT automation or time-based activations. If power cuts, the solenoid valve will keep its current state and allow manual switching, which makes it either a normally open or normally closed unit. This then offers the extra benefit of using minimal power, as it only needs to be energised when activating or deactivating the valve, and this even makes it a great choice for battery-powered valves, which may seem odd at first, but could offer fantastic benefits in remote or temporary locations in which power is not always available. Using your Raspberry Pi or Arduino microcontroller with your new DN20 Solenoid Valve, you can create an automated agricultural system, smart home taps and fisheries.

Finally, if this awesome electro valve sounds like a cool product, but you’re looking for an electro valve with a larger pipe fitting, consider taking a look at the DN15 Electro Valve, which is made for pipes with internal diameters of 15mm rather than 20mm.
