Water Regulator

I've found a creative way to repurpose an old valve case by attaching it to a servo adapter, allowing for an adjustable valve that can be controlled with a servo. It's essential to loosen the tension on the valve before installing the servo, or you may run into trouble with smooth operation. I loosened mine by a hair, and voilà! It works like a charm. This unique valve is exactly 21mm in diameter on its exterior.
