This little plastic valve allows precise control of flow rate, from a steady stream to one drip every few seconds. All plastic construction is saltwater safe. Works well with 1/4" OD (1/8" ID) polyethylene tubing.
Used this micro valve on a custom built kalkwasser doser. Allows you to adjust drip rate precisely and does not clog. Good quality plastic so it doesn't feel flimsy. Overall good product!
