I needed a watering valve that could be controlled with arduino. I did not want to use an electromagnetic valve.

I used the following elements for construction:
1) garden hose tap quick connector:

2) tact switch KW11-3Z:

3) gear motor with high torque JS-530

2019.09.03 After three months of operation, the valve cover was damaged.
I added a reinforced valve cover with better grip. I suggest increasing the filling to 30-40%.
Cover A and B are mirror images
