Fisherr655 and 655R Actuators

for Self-Operated Control

Fisher 655 and 655R diaphragm actuators, in

combination with Fisher valves, provide control for a

wide variety of pressure regulation applications. The

655 is used for pressure reduction service on

push-down-to-close valves, and the 655R is primarily

for pressure relief use on push-down-to-open valves.

These actuators may be either self-operated or

remote-loaded.

Features

Versatility–Typical industrial service includes

pressure control of water, steam, oil, gas, and other

fluids. Actuators can be operated by pneumatic

switches, solenoid valves, pilot valves, or remote

panel loaders for shutoff service.

Large Valve Body Selection–easy-e valves up

throughtheNPS4(NPS6forFisherEAanglevalves)

with wide choice of end connections, flow

directions, flow characteristics, valve plug designs,

and seating constructions can be specified.

Broad Actuator Spring Selection–Spring of the

proper rate is available for nearly any control valve

application. Spring selection procedure is quick and

accurate.

Severe Service Capability–Rugged yoke and casings

help provide stability and corrosion protection.

Fast Acting– Direct-operated configuration

provides faster speed of response.

6. Average for minimum and maximum pressures at zero and 0.25 inch travels.

Installation

These regulators may be installed in any position, as

orientation is not a problem. But for steam service, the

control line should be installed so that condensate

drains back into the diaphragm casing, thus

maintaining a water seal on the diaphragm. A strainer

(such as the Fisher 262K) is always recommended

ahead of the valve body to protect body and trim from

damaging particles.

Dimensions are given in figure 1. Refer to the

appropriate instructions before installing the

regulator.

Ordering Information

When ordering, specify:

1. All information requested in the Ordering

Information section of the valve body bulletin.

2. Actuator type number and size

3. Actuator travel

4. Valve plug stem diameter and connection size

5. Desired regulator orientation in pipeline

6. Magnitude and type of remote loading pressure, if

applicable (for instance, 3-15 psig controller output

signal)

7. Desired actuator options

Total Capability of Fisher

655-ED

The following charts (figures 2 through 11) show the

complete capability of the 655-ED, including travels

greater than 0.25 inch. Included are charts for Cv,C

g,

and Csfor the ED valves of various sizes and charts for

various casing sizes for the 655 actuator.

Anexampleontheuseofthechartsfollows:

1. Refer to the chart showing the Cvfor the ED design.

Assume your customer says his normal Cvis 37, but

can vary from 30 to 44 and the customer wants to

control at 110 psi. The NPS 2 will fit this quite well and

atthetopofthechartyouwillnoticethatthisrequires

a travel from 0.25 inch to 0.375 inch with the normal

travel at 0.3125 inch.

2. Next, refer to the curve on the 655-ED, A-CASING

chart of diaphragm pressure versus valve travel. Enter

the chart at 0.3125 inch valve travel and proceed up

until you intersect the 110 psi pressure. You will note

that spring drawing 1F7143 is at this intersection. You

can then readily see that when the flows vary, the

pressure will vary from approximately 118 psi to 105

psi as the valve travels from 0.25 inch to 0.375 inch.
