Instruction Manual Large ET and ED Valves July 2017 D103553X012 For ED/EWD and ET-C/EWT-C Valves, using the below procedure, disassemble the seat ring from the valve body: a. Unscrew the seat ring cap screws (key 49). b. Install 3/8”-16 eye bolts with a minimum threaded length of 0.5 inches into the two equally spaced tapped holes in the top of the seat ring (key 9). - Page 13 Instruction Manual Large ET and ED Valves July 2017 D103553X012 For ET/EWT Valves Equipped with HTS1 Seals 1. Carefully pry the plug retaining ring (key 27) from its groove in the valve plug (key 2A). Then remove the plug seal ring (key 28), backup ring (key 29), and anti-extrusion ring (key 63).
- Page 14 Instruction Manual Large ET and ED Valves July 2017 D103553X012 3. Referring to figure 3, locate the 1/4-inch diameter hole in the groove where the piston ring was installed. 4.

Page 15: Seat Ring Maintenance
Instruction Manual Large ET and ED Valves July 2017 D103553X012 14. Each new piston ring (key 6) is furnished as a complete ring, and each must be broken into two approximately equal portions. Do this by placing the ring on edge on a smooth, hard surface and striking the ring squarely with a hammer. - Page 16 GG43649X012 24.00 1. Contact your Emerson sales office or Local Business Partner for this tool and dimensions. For ET/EWT Valves 1.

Page 18: Bore Seal Retrofit
Additional actuator thrust is required for a valve equipped with the bore seal. When installing the bore seal in an existing valve, contact your Emerson sales office or Local Business Partner for assistance in determining new actuator thrust requirements. The bore seal retrofit will require a new valve plug and stem assembly (key 2), bore seal (key 64), and piston ring (key 6). -
Page 19: Assembly
This is especially critical in ED/EWD valves equipped with the bore seal. If after assembly the rated shutoff class is not attained your Emerson sales office Local Business Partner can provide further assistance. -
Page 20: Parts Ordering
WARNING Use only genuine Fisher replacement parts. Components that are not supplied by Emerson Automation Solutions should not, under any circumstances, be used in any Fisher valve, because they may void your warranty, might adversely affect the performance of the valve, and could cause personal injury and property damage. - Page 21 Instruction Manual Large ET and ED Valves July 2017 D103553X012 ENVIRO-SEAL Packing Kits Repair kits include parts to replace the “soft” packing materials in valves that already have ENVIRO-SEAL packing arrangements installed or in valves that have been upgraded with ENVIRO-SEAL retrofit kits.
