Parts Ordering

Each valve assembly is assigned a serial number that can be found on the valve body. Refer to the serial number when

contacting your

Emerson sales office

When ordering replacement parts, refer to the serial number and to the 11‐character kit number for each kit required

from the following list. Kits for valves with shaft sizes greater than 38.4 mm (1‐1/2 inch) will not be available, however,

ENVIRO‐SEAL parts may be ordered separately. Consult your Emerson sales office for details.

Retrofit kits include all parts required for installation of the ENVIRO‐SEAL packing system into existing rotary and high

performance butterfly valves. Retrofit kits are available for single PTFE or graphite packing. See tables 5 through 7 for

retrofit kit part numbers.

The 8510B has two packing boxes, one at the actuator end and one at the outboard end. Select a kit from each column

of the following table.

Packing boxes in V500 and CV500 valve bodies may be deep drilled, (at one time standard on all CV500 and always

available as an option). If the valve body being retrofitted has a deep packing box, use the longer packing box ring (key

107) from the original packing. Discard the 3 mm (1/8‐inch) packing box ring from the retrofit kit. If a replacement

packing box ring (long, key 107) is required, refer to the valve instruction manual for parts, or consult your Emerson

sales office. Refer to figure 2, the view titled: Double PTFE Packing with Leakoff—Optional Deep Packing Box.

Note

1. Use the existing long packing box ring (key 107) that was furnished with the original valve when installing the retrofit kit in:

•V200 NPS 8 and 10 valves, or

•V150 and V300 NPS 8, 10, and 12 valves

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.
