No. SS2-8113-0200 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. Figure 5 Structural drawing of micro flow trim Figure 2 Bellows Type by Temperature and Pressure Ranges Figure 3 Temperature and maximum differential pressure range for soft-seat Note) Bellows type are classified into Formed bellows type I, II and welded bellows by temperature and pressure ranges. Please refer to No. SS2-BSL100-0100 about detail of bellows specification. Note) If there is any possibility to cause erosion due to saturated steam or superheated-water, use the metal seat. Figure 4 Temperature / normal differential pressure ranges requiring Stellite 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) SUS440C 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, Stellite faced valve plugs or 440C hardened Stainless steel valve plugs are standard. a.
