Introduction

Scope of Manual

This instruction manual provides installation, adjustment, maintenance, and parts ordering for the Fisher 655 and

655R actuators and the top‐mounted handwheel. Refer to separate instruction manuals for information about valves

and accessories used with these actuators.

Do not install, operate, or maintain 655 or 655R actuators 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

655 and 655R Actuators Instruction Manual December 2010 D100305X012 For Push‐Down‐To‐Close Valves: a. Place the actuator part way over the valve stem. Then, place the yoke locknut over the valve stem, and slide the travel indicator disk (key 11, if used) on top of the hex nuts (key 12). b. Set the actuator onto the valve body. The length of the valve stem will prevent the actuator yoke (key 7) from sitting on the bonnet properly.

After correct travel has been obtained, tighten the hex nuts (key 12) against the actuator stem (key 8), and tighten the yoke locknut with a hammer and punch. Note Changing the spring adjustment will not change the actuator pressure range for that particular spring (see table 2).

655 and 655R Actuators Instruction Manual December 2010 D100305X012 Adjustment For Pressure‐Reducing or Pressure‐Relief Service The actuator is factory‐set as specified on the order, and the pressure range is stamped on the nameplate. If a pressure setting other than the one specified is desired, change the pressure setting by following the procedures listed below. Be sure to change the nameplate to indicate the new pressure setting.

Instruction Manual 655 and 655R Actuators D100305X012 December 2010 D Do not remove the actuator from the valve while the valve is still pressurized. D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal injury. D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the actuator cannot suddenly open or close the valve.

655 and 655R Actuators Instruction Manual December 2010 D100305X012 a. Loosen the two hex nuts (key 12). b. Loosen the yoke locknut (figure 3) with a hammer and punch, and unscrew it from the valve bonnet. c. While lifting the actuator so that the valve plug is not forced against the seat, rotate the entire actuator until the actuator stem disengages completely from the valve plug stem. For Push‐Down‐To‐Open Valves: a.

Secure the diaphragm plate (key 4) to the actuator stem (key 8) with the cap screw (key 3), and install this assembly into the actuator. Install the diaphragm, making sure that the patterned side of the diaphragm is next to the diaphragm plate. Note When replacing the upper diaphragm casing (key 1), be sure there are no wrinkles in the diaphragm that might cause the diaphragm to tear or allow leakage. 6.

Insert the handwheel stem into the handwheel body (key 28, figures 6 and 7; key 142, figure 5); then, screw the hex nut (key 27, figures 6 and 7; key 137, figure 5) onto the handwheel stem. 4. Install the handwheel (key 25, figures 6 and 7; key 51, figure 5) and washer (key 24, figures 6 and 7; key 134, figure 5) onto the handwheel stem, and secure it with the hex nut (key 22, figures 6 and 7; key 54, figure 5). 5.

Install the upper diaphragm casing (key 1), and install the cap screws and nuts (keys 19 and 20). Tighten in the following manner. 15. The first four bolts tightened should be diametrically opposed and 90 degrees apart. Tighten these four bolts to 13 NSm (10 lbfSft). 16.
