Material And Internal Structures
- The above is standard configuration structure, the valve seat is metal to metal, and we can still provide strengthed trim with stellite alloy coating. For specific applicable temperature, we have more reasonable bolts, nuts for choose.
- PTFE v-shaped ring stem packing is the standard configuration and can also choose flexible graphite.
- Standard body material is carbon steel and stainless steel, and we can still provide various high corrosive-resistance alloy materials.
