The new S30 valve for your keg comes in high grade stainless steel.
The S30 valve can be equipped with a small piercing pin if you want to use 8g CO2 bulbs (use the bulb holder below to screw these onto the valve). You can insert and remove the pin and easily switch between using S30 cylinders and 8g bulbs.
For convenience, the valve comes in two versions – either pre-equipped with a piercing pin for 8g bulbs, or plain for use with S30 cylinders. Whichever version you get, it is as simple as removing/inserting the pin to change version.
When you remove or insert the pin, you need to temporarily remove the small o-ring inside first (use a knife or small screwdriver – carefully).
