It is used as a water supply valve to the ultrasonic humidifier.
Because the clean tube is used as a water supply piping, cut it so that water supply is stopped with this valve and use it. Just by inserting the tube, it is very easy to set the valve, and even when you remove it you can pull the tube by pulling the stopper and it is very handy.
Although it is used at 4 kg / cm 2, opening and closing of the valve is smooth and light. In addition, leakage does not occur and pressure is kept even the next day. As expected, it is a performance that makes me think PISCO.
