( trim # 1 is still used for API603 gates as well as globe & check valves ).

7 Also, even though API no longer references trim # 2, for API603 gate , globe & check, (and in some commodity API600 gate valves in lower classes and under 300NB) it is still manufactured as it is specified by clients. A HB (formerly BHN) is the symbol for Brinell Hardness per ASTM Free Machine grades of 13Cr are Body and disc seat surfaces should be 250HB minimum with a 50HB minimum differential between the body and disc seat Manufacturer s standard Differential hardness between the body and disc seat surfaces is not Case hardness by nitriding to a thickness of mm ( in.) A WS ECoCr-A or AWS ERCoCr-A: This classification includes such trademark materials as Stellite 6 , Stoody 6 and Wallex 6.

8 For Plasma Transfer Arc Welding (PTAW) process powder with the metallurgy equivalents to UNS R30006 can also be used. CoCr-E (Stellite 21 * or equal) may be used only with purchaser approval and typical CoCr-E alloys include AWS ECoCr-E or AWS Manufacturer s standard hardfacing with a maximum iron content of 25%.J Hardness differential between the body and disc seat surfaces shall be the manufacturer s Manufacturer s standard with 30 Ni Typical backseat weld deposit Per manufacturer s standard if not Hard faced, 250 HB minimum if Hard trim materials, including stem and base material for HF trim items, shall have a corrosion resistance and temperature limit at least equal to the valve body s corrosion resistance and pressure temperature rating.

9 * This term is used as an example only, and does not constitute an endorsement of this product by Note: Data provided in this CHART is for informational purposes only. Always consult current API publications to verify information (as of Feb 2017 API Table 8). Note API600 is only designed for steel bolted bonnet gate valves and specific hardness requirements. Do not literally apply to globe & check valves . Australian Pipeline Valve recommend that customer s engineers analyse SERVICE requirements and specify the materials they consider optimum for their SERVICE conditions. Temperatures shown will vary depending on SERVICE applications, pressure and media type. The API600 trim CHART specifications are primarily designed for API600 gate valves .

10 For API603 gate valves as well as globe valves and check valves , the same trim numbers are more loosely applied (API603 does not reference a trim CHART as of 2017). In regard to globe and check valve, the hardness differentials shown above on the disc and seat aren t mandatory by many end users (and manufacturers are not required to follow the latest version of API600 unless client requires it) as wear, gauling, sticking etc., is not such an issue with globe & check valves . In large parts of the world globe valves and check valves are ordered as BS spec not API (BS spec is now converted to ISO specification). Many check valves are also ordered to API6D specifications. In regard to API602, the same identical trim CHART is specified in the latest version of API602.
