1 DATE: 09/08/00 PAGE 1 OF SCOPE: 1.1 TO PROVIDE A METHOD OF SELECTING "O" RINGS FOR VALVE SERIES 1900, 1970, 1990, 2900, 19000, 3900 & 4900 VALVE APPLICATIONS AND 8 DIGIT PART NUMBER REPLACEMENTS FOR 7 DIGIT PART NUMBERS. 1.2 REVISION TO THIS INSTRUCTION MAY REQUIRE A CORRESPONDING REVISION TO DRAWING 310 AND INSTRUCTION EG "O" RING SELECTION FOR NEW VALVES: 2.1 MATERIAL SELECTION IS A FUNCTION OF VALVE SET PRESSURE, RELIEVING TEMPERATURE (FOR FIRE APPLICATIONS THE VALVE OPERATING TEMPERATURE IS USED) AND FLUID. 2.2 MATERIAL SELECTION IS ACCOMPLISHED AS FOLLOWS: REFER TO TABLE FOR 2900, 3900 & 4900 SERIES MAIN VALVES, THE FOLLOWING MATERIALS ARE STANDARD: STEAM SERVICE IS. ONLY ALTERNATIVE IS EPR FOR TEMPERATURES UNDER 400EF AND PRESSURES BELOW 50 PSIG GAS, AIR, AND LIQUID SERVICE IS 70 DUROMETER NITRILE ONLY DEVIATE FROM STANDARD IF TEMPERATURE, PRESSURE, OR MEDIA REQUIRE IT LOCATE VALVE FLUID AND READ THE APPLICABLE O-RING MATERIALS. FOR FLUIDS NOT LISTED, THE CUSTOMER MUST SPECIFY THE O-RING MATERIAL.

2 DATE: 09/08/00 PAGE 2 OF REFER TO TABLE 2. LOCATE THE VALVE TYPE AND SET PRESSURE AND READ THE "O" RING DUROMETER AND SIZE REFER TO TABLE REPLACEMENT PARTS ORDER: LOCATE THE MATERIAL AND DUROMETER AND READ THE MATERIAL DESCRIPTION, TEMPERATURE LIMITS AND MATERIAL CHECK THE TEMPERATURE LIMITS FOR THE SPECIFIED MATERIAL. REPEAT FOR APPLICABLE MATERIALS IF TEMPERATURE LIMITS ARE ECEEDED. FOR SOME CONDITIONS OF FLUID, PRESSURE AND TEMPERATURE "O" RINGS CANNOT BE OFFERED. 3.1 EFFECTIVE SEPTEMBER 1986, "O" RINGS FOR ALL SAFETY RELIEF VALVES HAVE BEEN PLACED ON DRAWING NO THE MATERIAL DESCRIPTION AND S HAVE BEEN CHANGED WHEN COMPARED TO DRAWING NO. 312 AND THE PREVIOUS DRAWING NO THE "O" RING SIZE HAS BEEN CHANGED FROM THE DRESSER TWO DIGIT TO STANDARD AS568A (AEROSPACE STANDARD) THREE DIGIT. "O" RING SIZES WHICH DO NOT CORRESPOND TO THIS STANDARD HAVE BEEN ASSIGNED A DRESSER TWO DIGIT WITH AN "S" PREFI. EAMPLE: S01 - SPECIAL "O" RING SIZE TO DRESSER DRAWING NO AN "N" SUFFI AT THE END OF THE PART NUMBER INDICATES "NUCLEAR SERVICE" WITH CONTROLLED BATCH IDENTIFICATION (CBI) WITH PHYSICALS (HARDNESS, TENSILE, AND ELONGATION). 3.2 MATERIAL SELECTION MATERIAL SELECTION MAY BE ACCOMPLISHED PER TABLE 4 OR PARAGRAPH SIZE SELECTION THE THREE DIGIT REPLACEMENT SIZE IS OBTAINED FROM TABLE
