Sealing type of pneumatic on-off valve

Thread Content

How can one determine the sealing type of a pneumatic on-off valve? The specification sheet indicates that the valve seat material is 316SS+STL, and the packing is PTFE. Can it be determined that it is a hard seal?

What was said upstairs is very simple, but it’s exactly the answer: if the valve seat is made of PTFE or a non-metallic material, it’s a soft seal; otherwise, it’s a hard seal
