What are the differences between Q41PPL and ordinary ball valves, and is its manufacturing cost higher than that of ordinary ball valves?
Reply #22018-03-21
With all other requirements being the same, the difference must lie in the fact that the valve seat is of PPL type
Reply #32018-04-20
The valve seat materials of the two are different; ordinary ball valves can be used at temperatures below 150°, while PPL ball valves can be used at temperatures below 300°
