Discharge Port Options (PRV9432):
* Safety valves without outlet tubing generally leave the discharge port information blank in the part number.
* “P” indicates a safety valve with no discharge port (e.g., PRV9432TP350).
* Discharge tube option: “P” indicates a connected discharge tube with no discharge port (e.g., PRV9432TP350P).
* If left blank, it means the safety valve has no discharge tube (e.g., PRV9432T350).
Discharge Port Options (PRV9434):
* Same as above: blank indicates no discharge port;
* “P” = with discharge tube, no discharge port (e.g., PRV9434TP350P);
* Blank = no discharge tube (e.g., PRV9434T350).
