Remark:
1. It is recommended that the appropriate seat material, providing a higher pressure & temperature, is selected, if you feel the standard material is borderline and you prefer a larger safety allowance.
2. For steam service, options available are PEEK, PTFE+50%SS, or Metal seat, depending on the service application.
3. Final selection of seat material is the user's choice, experience & responsibility.
