WhatsApp: +86 18838072829I can understand the confusion, because when the valve is in the "open" position, there is no visual cue that there is any kind of ball residing in the valve. So, I thought I'd create a quick post with pictures to illustrate how the "ball" in a gas ball valve operates! Remember that turning clockwise closes the valve, and counterclockwise opens it.
WhatsApp: +86 18838072829The vapour passes to atmosphere through a gauze flame trap. Drop in tank pressure compared with that of the outside atmosphere will make the small valve open downwards to equalize internal pressure with that outside. Pressure vacuum valve or pv valve can relieve moderate changes in tank pressure due to variations in temperature and vapour quantity.
