Azbil Corporation No. SS2-AGV200-0300 - 5 - 3-1-10 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 10 Temperature and normal differential pressure ranges that require a Stellite Note)1) 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. 2) 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 seats Note)1) When there is a possibility of erosion by such fluids as saturated steam and heated water please use metal seats. 2) The material of washing treatment for oil-free of the wetted parts (inside the body) is PTFE with galss. a. With gude bushing b.
