can we use ss316 or 410 Ball with PEEK Seats.
knowing the PEEK is a hard material will it cause any problems with SS316 or 410 Ball.
PEEK can scratch the ball made of soft material like SS316??

Hi quiinces,

In my opinion, PEEK material can never cause scratch on SS/F6a ball, it is softer than the steel. PEEK is commonly used as the seat materials for high pressure use.

People have been making 316 ball valves with PEEK seats for at least 20 years.
