PS and P1S Series - Soft Seat design Soft seat for bubble-tight shutoff of general purpose applications. (PS soft seat material is RTFE. P1S soft seat material is G2TFE). PF and P1F Series - Firesafe seat design Primary soft seat for bubble-tight shutoff backed up by secondary 316L SST firesafe seat. Secondary firesafe seat provides Class V shutoff when primary soft seat is compromised in a fire event. (PF soft seat material is RTFE/316L SST. P1F soft seat material is G2TFE/316L SST). PM and P1M Series - Metal seat design for specialized applications 316L SST seat for Class V shutoff of high temperature applications. Standard disc with this series is 316 SST with HCr. PH and P1H Series - Metal seat design for high temperature Inconel 625 seat and 316 SST with Stellite disc is recommended for extreme temperatures.
