Fisherr 2052 Diaphragm Rotary Actuator

Fisher 2052 spring-and-diaphragm rotary actuators are
used on rotary-shaft valve bodies for throttling or
on-off applications. The 2052 may be used for
throttling service with a positioner, or it may be used
for on-off service without a positioner. The 2052 has an
ISO 5211 mating interface that allows installation to
non-Fisher valves. Refer to separate bulletins for valve
and positioner information.

Features

61.1:2052

n Compact design, smaller actuators-- Ensures

reduced valve/actuator envelope dimensions
leading to greater mounting versatility for both
skids and process plants, where space is at a
premium.

n Compatible with DVC2000, DVC6200, and

DVC6000 digital valve controllers; and 3610J and
3620J positioners-- The new actuator allows

linkage-less feedback, via a contact-less magnetic
array, from the lever to the end-mounted DVC2000.
Integral window mounting of the DVC6200,
DVC6000, 3610J, and 3620J is also available.

n Clamped lever to reduce lost motion-- The clamping

of the lever onto a splined valve shaft, coupled with
the single pivot linkage, reduces lost motion
between the actuator and the valve. The typical
cumulative deadband for a Fisher rotary control
valve assembly results in 0.5% or less variability.

n No bench set required-- The new nested spring

design requires no bench set. This also simplifies the
actuator selection process, see table 3.

n ISO 5211 mounting with optional insert-- The

actuator can now be mounted directly onto
non-spline shafts, such as Square and Double D. This
allows the actuator, with its enhanced control, to
mount on a wider range of valves conforming to ISO

5211.

FIELDVUE™ DVC6200 Digital Valve Controller

n Adjustable travel stops standard-- Provides the

ability to adjust or change the travel range by 30
degrees in either direction without removing the
actuator or the addition of extra parts.

n Fail-safe mechanism contains no aluminum-- All

parts in the fail-safe mechanism (made of steel, cast
iron, and ductile iron) ensure the actuator will
maintain safety integrity in the event of a fire.

n Powder paint as standard-- The Emerson Process

Managementt powder paint finish offers an

excellent corrosion-resistant finish to all external
steel and cast iron parts.

n NAMUR VDE/VDI 3845 bolt pattern for accessory

mounting-- Meeting the global standard ensures

compatibility for most accessories, enabling quick
and easy mounting.

n Field reversible, right- or left-hand mounting-- The

actuator/valve assembly action can be converted
from push-down-to-open to push-down-to-close, or
vice-versa, without additional parts.

n Declutchable and top-mounted handwheels--

Available for all sizes.

Options

Top-Mounted Handwheel: For infrequent use as a

manual actuator (see figure 2). For repeated or daily
manual operation, the unit should be equipped with a
declutchable handwheel actuator.

Declutchable Handwheel Actuator: An end-mounted
manual actuator can be used to provide on-site control
and to provide override capabilities. See bulletin

61.8:1078

declutchable handwheel is not compatible with the
lockout option on the size 2 and size 3 actuators.

Limit Switches:
for one or two single-pole, double-throw contacts, or

J GO proximity switches for one or two single-pole,

double-throw contacts are available. See separate
bulletins for limit switch information.

Position Indicating Switch: TopWorxt DXP M21GNEB
switch for one through six single pole, double throw
switch contacts are available. See separate bulletin for
position indicating switch information.

Positioner: For precise positioning of the valve control
element, the actuator should be equipped with a
positioner. For additional information, contact your
Emerson Process Management sales office with
complete service conditions.

Optional Lockout Option: An actuator locking
mechanism is available, which can be used to keep the
actuator in a locked position (the same as the
spring-fail position) during maintenance. The padlock
is customer supplied. The lockout option on the size 2
and size 3 actuators is not compatible with the
declutchable handwheel.

Cold Service Construction: For services with ambient
temperatures down to -60_C (-76_F). This
construction is suitable for cold climate regions per
GOST 15150. Contact your Emerson Process
Management sales office for details. Note that the
current SIL certification for the 2052 actuator is only
relevant for the standard temperature ratings shown in
table 1. Not available with the top-mounted
handwheel option.
