Introduction

Scope of Manual

This manual provides installation, adjustment, and maintenance information for Fisher 9500 butterfly valves. These

valves use splined shafts with actuator-mounted brackets and linear-motion actuators (see figure 1). Refer to separate

manuals for instructions covering the power actuator or the manual handwheel actuator, positioner, and other

accessories.

Do not install, operate, or maintain 9500 valves 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.

Description

The 9500 valve is a fully lined butterfly valve for use with corrosive process fluids or wherever stringent shutoff is

required. The nitrile or PTFE liner completely isolates the valve body and shaft from the process fluid. The valve is

available with conventional or FISHTAIL™ disc designs.

NPS 6 to 10 valves must not be used with slip-on flanges unless flange adaptors are used to support the liner. When using slip-on flanges with other sizes, be certain the valve is carefully centered to ensure that the partial O-ring faces are in full contact with the adjacent flanges. c.

Tighten both thrust-plate cap screws (key 10) 1/4 turn on one side (the side where shaft leakage is occurring). CAUTION To avoid excessive side thrust on the disc and possible liner damage, tighten cap screws on both sides of the valve alternately and in 1/4-turn increments. Do not over-tighten by continuous turning or by tightening one side only.

Tandem Linkage Adjustment for Three-Way Valve Assemblies FLOW ROTARY ACTUATOR HOUSING POWER VALVE CONNECTING ROD ASSEMBLY SLAVE VALVE FLOW B2144-1 FLOW FOR SPLINED VALVE SHAFTS Linkage If the linkage between the power actuator and valve is improperly adjusted, the actuator may reach the end of travel before (or after) the disc reaches the fully closed position. This could result in leakage past the disc.

Instruction Manual 9500 Valve D100380X012 July 2012 If the adjustment is being performed with the three-way valve assembly out of the line, temporarily bolt the valve bodies to the tee to compress the liner faces until there is metal-to-metal contact between the valve bodies and the tee. Check the rotation of the power valve disc per instructions in the Linkage section. If necessary, adjust the linkage between the actuator and the power valve.

Instruction Manual 9500 Valve D100380X012 July 2012 8. Remove the liner (key 2) from the valve body. Some 9500 valves have the liner bonded to the valve body. If the valve has a bonded liner, burn or chip out the liner. To strip the liner out with solvent, use Dynasolve 185, or equivalent solvent. (Dynasolve is a product of DYNALOYt Inc.). Cover the valve with solvent bath or enclose the solvent bath around the liner. Remove all adhesive after the liner has been removed. Table 5.

Omit the following steps 4 through 8 if a new disc and shaft assembly is to be installed or if the old disc and shaft are to be reused. Use new taper pins whenever the disc has been removed. CAUTION If a new disc is required, a complete disc/shaft assembly must be purchased to avoid damage to valve parts.

Instruction Manual D100380X012 9500 Valve July 2012 Actuator Mounting 1. Refer to the appropriate actuator instruction manual to determine the desired actuator mounting style and position. With the valve out of the line, mount the actuator on the valve per instructions in the actuator instruction manual. 2. To determine the fully closed disc position, measure the distances between the valve face and the top and bottom edges of the disc as shown in figure 2.

9500 Valve July 2012 Instruction Manual D100380X012 Changing Disc Rotation and Action Disc rotation can be changed from 0-90 degrees or vice versa by changing travel stops in the actuator and, if necessary, changing the position of the lever on the splined valve shaft. Action can be changed from push-down-to-open to push-down-to-close by removing the actuator and remounting it in the alternate mounting style.
