Fisherr 655 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.

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:
4
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

Anexampleontheuseofthechartsfollows:
1. Refer to the chart showing the C
Assume your customer says his normal C

v
is 37, but
v
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.
