The inside surface of the cage or cage/baffle assembly (key 3), or cage retainer (key 31), is critical for smooth operation of the valve plug. -
Page 13: Valve Plug Maintenance
Instruction Manual ET Valve D100398X012 November 2017 Except with respect to the ENVIRO‐SEAL Bellows Seal Bonnet assembly, with metal‐seat constructions, lapping seating surfaces of the valve plug and seat ring or liner (keys 2 and 9, figure 16, 17, or 20) can improve shutoff. (Deep nicks should be machined out rather than ground out.) Use a good quality lapping compound of a mixture of 280 to 600‐grit. - Page 14 Instruction Manual ET Valve November 2017 D100398X012 For the two‐piece seal ring, The ring cannot be reused because it is a closed ring which must be pried and/or cut from the groove. Once the seal ring is removed, the elastomeric backup ring (key 29), which is also a closed ring, can be pried from the groove.
