Introduction

Scope of Manual

This instruction manual includes installation and parts information for Fisher ENVIRO-SEAL live-loaded packing

systems(seefigure1).ThesesystemsareavailableforFisher 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

Process Management sales office before proceeding.

Instruction Manual ENVIRO-SEAL System - Rotary Valves D101643X012 November 2011 Installation Use these instructions to install ENVIRO-SEAL packing in valves that have standard packing, or when inspecting or replacing ENVIRO-SEAL packing. If you are changing the packing system material from standard graphite to ENVIRO-SEAL graphite or ENVIRO-SEAL PTFE packing, the packing friction for ENVIRO-SEAL packing will be lower than it was for the standard packing.

ENVIRO-SEAL System - Rotary Valves Instruction Manual November 2011 D101643X012 You must remove the actuator from the valve when you install ENVIRO-SEAL packing systems. To allow proper readjustment of the valve disc position, it is recommended that you remove the valve from the pipeline. Refer to appropriate valve and actuator instruction manuals. WARNING If a spring-return actuator is used, be sure the actuator spring is resting on its travel stop.

ENVIRO-SEAL System - Rotary Valves November 2011 Instruction Manual D101643X012 Note ENVIRO-SEAL PTFE packing systems can be used in either vacuum or positive pressure service. It is not necessary to reverse ENVIRO-SEAL PTFE packing components in vacuum service. Make sure that the Belleville springs are stacked properly and packing box parts are assembled in the correct order (see figure 6). Packing parts cannot function properly if the Belleville springs or other packing parts are not stacked correctly.
