Tank truck ball valve models
Thread Content
A few days ago, my boss asked me to prepare for replacing the valves on the liquid ammonia tank trucks. I went to take a look, and here’s what it looks like: ACQA-25P and CQA41F-25P – they are both from the same manufacturer, namely Beijing Valve Factory. 25 should refer to pressure, which is 2.5 Mpa; P probably refers to stainless steel. I don’t understand the first few points; please give me some advice (note: not criticism)
This number is the manufacturer’s own designation; it is not standard. You can contact the manufacturer to ask about it
