Azbil Corporation No. SS2-AGV200-0001 - 5 - 3-1-10 Structural drawing of trim and body/trim material combinations Following table shows typical body/trim material combinations. Please contract us about materials that are not listed in the table. Table 7 Body, plug and seat ring material Figure 9 Development view of AGVB/AGVM Material combination Temperature ranges (°C) SUS 316 -5 to +300 -45 to +300 -45 to +300 SUS 316 Stellite -5 to +400 -196 to +400 -196 to +400 SUS440C -5 to +400 -45 to +400 --- SUS 316 soft seat -5 to +230 -45 to +230 -45 to +230 SUS 316 Stellite face -5 to +400 -196 to +400 -196 to +400 SUS 316L --- -45 to +300 -45 to +300 SUS 316L Stellite --- -196 to +400 -196 to +400 Body material JIS SCPH2 SCS13A SCS14A ASTM A216WCB A351CF8 A351CF8M Note) *1: Parts that adjust flow (such as a plug and a seat ring) are referred to as the valve trim. Figure 10 Temperature and normal differential pressure ranges requiring a stellite Note) 1) Depending on the methods of hardening treatment, stellite welding or SUS440C is available. 2) For valves for cavitation/flashing service, oil-proof service, or tight shutoff service, a stellite is recommended regardless of process fluid temperatures or differential pressures. 3) For valves for cavitation/flashing service for water or for valves for superheated water above 100 oC, SUS 440C is recommended. Figure 11 Temperature and maximum differential pressure ranges for soft seat Note) 1) When there is a possibility of erosion by such fluids as saturated steam and heated water please use metal seats. 2) WIth the fluid connecting parts (inside the body) the material of the seat which oil-proof washing treatment had been completed is PTFE entered with glass.
