Scope of Manual
This instruction manual provides installation, adjustment, maintenance, and parts ordering for the Type 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 and 655R actuators without first D being fully trained and qualified in valve, actuator, and accessory installation, operation, and maintenance, and D carefully reading and understanding the contents of this manual. If you have any questions about these instructions, contact your Emerson Process Managementt sales office before proceeding.
Description
Type 655 and 655R actuators (figure 1) are pressure-actuated, spring-and-diaphragm actuators used in conjunction with various valves to provide
control for a wide variety of pressure regulation applications. Type 655 actuators are used for pressure-reducing service when mounted on push-down-to-close valves such as the Design ED and ET valves. Type 655R actuators are used for pressure-relief service when mounted on push-down-to-open valves such as the Design EDR and ETR valves. Both types are self-operated and direct-acting; that is, increasing pressure in the diaphragm casing forces the actuator stem downward, and decreasing the pressure allows the actuator spring to lift the actuator stem upward.
Note
Neither Emerson, Emerson Process Management, nor any of their affiliated entities assumes responsibility for the selection, use and maintenance of any product. Responsibility for the selection, use, and maintenance of any product remains with the purchaser and end-user.

Specifications
Specifications for the Type 655 and 655R actuators are shown in table 1. Information for a specific actuator is also found on the nameplate of that actuator.
Installation
WARNING
To avoid personal injury or property damage caused by bursting of pressure-retaining parts, be certain the service conditions do not exceed the casing pressure limits listed in table 1. Use pressure-limiting or pressure-relieving devices to prevent service conditions from exceeding these limits.
2
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal injury.
Check with your process or safety engineer for any additional measures that must be taken to protect against process media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this instruction manual.
Type 655 and 655R actuators are normally shipped mounted on a valve. Refer to the appropriate valve instruction manual when installing the valve in the pipeline. If the actuator is shipped separately or if it is necessary to mount the actuator on the valve, perform the procedures described in the Actuator Mounting portion of this section.

Form 1292 July 2007
655 and 655R Actuators
CAUTION
To avoid premature wear of the diaphragm due to debris in the pressure line to the diaphragm, install a strainer in the pipeline ahead of the regulator or relief valve.
Before installing the actuator, inspect it for any damage. Also, keep any adjacent piping clean and free of pipe scale or other debris that could possibly disrupt service. It is recommended that a strainer be installed in the pipeline ahead of the regulator or relief valve to protect it while in service. And a conventional three-valve bypass (see figure 2) should be placed around the regulator or relief valve to permit continuous operation when it is being installed or repaired.
Actuator Mounting
The actuator may be installed either above or below the pipeline.
plate (key 4) against the upper diaphragm casing (key 1).
2. Perform the following steps as appropriate for either push-down-to-close or push-down-to-open valve action.
CAUTION
In the following procedures, do not rotate the valve plug while it is seated since this may cause damage to the seating surfaces and thereby allow excessive leakage. Also, during travel adjustment, use tools carefully to avoid damaging the valve plug stem. A damaged stem could cut the packing and allow leakage.
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).
CAUTION
In steam service applications, avoid premature wear of the diaphragm, due to high temperature steam, by installing the valve with the actuator positioned below the pipeline.
If the regulator or relief valve is to be used for steam service, the valve should be installed with the actuator positioned below the pipeline, and the control line should be sloped down toward the diaphragm casing. This is to ensure that any forming condensate will maintain a water seal to protect the diaphragm.
The following procedure describes how to mount the actuator on either a push-down-to-close or a push-down-to-open valve so that the actuator stem and valve stem thread engagement will allow full travel and proper shutoff. Refer to figure 3 for actuator mounting components. Key numbers refer to figure 4 unless otherwise stated.
1. Turn the adjusting screw (key 10) into the yoke (key 7) to force the diaphragm (key 2) and diaphragm
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. Measure the distance from the bottom of the actuator yoke to the mating shoulder on the bonnet, and then add the valve plug travel to this measurement.
c. Raise the actuator so the valve plug can be lifted off the seat ring.
Note
Either turn the actuator, or tighten the hex nuts together, and use a wrench on the hex nuts to turn the valve plug and stem assembly.
Thread the valve stem into the actuator stem the distance measured in the previous step.
d. Lower the actuator onto the valve body bonnet, and tighten the yoke locknut.
e. Connect the pressure control lines as described in the Loading Connection portion of this section.
