Figure 4. Maximum Pressure/Temperature Ratings for Soft Seal, NOVEX Seal and Phoenix III Seal, CL150 and CL300
Note
Because of potential erosive and premature seal failure that can occur, throttling PTFE seals at differential pressures greater than 300 psid at disk angles less than
20 degrees open is not recommended.
Temperature limitations do not account for the additional limitations imposed by the backup O-ring used with this seal. To determine the effective temperature
limitation of the appropriate seal backup O-ring combination, refer to table 2.
