No. SS2-8114-0200 Azbil Corporation - 6 - Structural drawing of trim and body/trim material combinations Following table shows typical body/trim material combinations. Please contact us about materials that are not listed in this table. Note) 1)When cavitation/flashing service, oil prohibitive service, or retention of valve-close performance is required, use of Stellite is recommended regardless of temperature or differential pressure. 2)440C hardened stainless steel is recommended for valves for cavitation/flashing service of water or for superheated service of water of higher than 100°C. 3)When rated Cv value is 0.16 or lower, faced valve plug or 440C hardened stainless steel valve plugs are standard. Figure 4 Temperature / Normal differential pressure ranges requiring Stellite a. Cv0.16 or over b. Cv0.1 or less Figure 5 Structural drawing of trim Table 4 The valve body material is carbon steel (SCPH2/A216WCB). ..Valve plug ..Seat ring SUS316 SUS304 SUS440C SUS316 Stellite SUS316 Stellite face SUS304 Stellite SUS304 Stellite face SUS316 soft seat SUS304 soft seat General General General Oil-free General Oil-free General Oil-free General Oil-free ..Valve stem SUS316 ..Guide bushing SUS440C SUS316 Stellite Solid Stellite SUS316 Stellite Solid Stellite SUS440C Solid Stellite SUS440C Solid Stellite ..Seat gasket Without (Design temperature: -17 to 230°C) SUS316 (PTFE coating) Without (Design temperature: -17 to 230°C) SUS316 (PTFE coating) Without SUS316 (PTFE coating) Without SUS316 (PTFE SUS316 (Design temperature: coating) above 230°C) SUS316 (Design temperature: above 230°C) ..Bonnet gasket SUS316 SUS316 (PTFE coating) SUS316 SUS316 (PTFE coating) SUS316 SUS316 (PTFE coating) SUS316 SUS316 (PTFE coating) Stellite 1470 {15} 981 {10} 490 {5} 0 -196 0 +100 +200 +300 Maximum differential pressure Fluid temperature ( C) kPa {kgf/cm2} Valve stem Guide bushing Bonnet gasket Valve plug Seat ring Seat gasket Valve stem Bonnet gasket Seat ring Valve plug Seat gasket
