Difference between "positive" and "side" of washing machine angle valve

The difference between the word "positive" and the word "side" of the angle valve of the washing machine is:

1. The miter valve is relatively convenient, easy to install and use, but it takes up a lot of space.

2. Side miter valve, the switch is at the side, which saves space and can be installed against the wall.

I hope my answer can help you.
