Attached is the CS part instrument datasheet for you review it, especially for control valve process data. In addition, in our piping class specify the seal for liquid waste on/off valve is metal seal (hard seal, leakage class V), but CS design for on/off valve is soft seal (valve seat is PTFE, leakage class VI), is it OK?
