Introduction
Scope of Manual
This instruction manual includes installation and parts information for Fisher ENVIRO‐SEAL live‐loaded packing
systems (see figure 1). These systems are available for Fisher rotary valves with 12.7 through 88.9 mm (1/2 through
3‐1/2 inch) shaft diameters. The system can be used with many rotary valves, as shown in tables 1 and 3. Refer to
appropriate valve and actuator instruction manuals for necessary information relating to the disassembly and
assembly of the valve and actuator. ENVIRO‐SEAL packing systems utilize a Belleville (coned‐disk) spring system.
Do not install, operate, or maintain the ENVIRO‐SEAL packing system, valve, actuator or accessories without being
fully trained and qualified in valve, actuator, and accessory installation, operation, and maintenance.
To avoid personal
injury or property damage, it is important to carefully read, understand, and follow all the contents of this manual,
including all safety cautions and warnings.
If you have any questions about these instructions, contact your Emerson
sales office before proceeding.
