Fisher® 2052 Diaphragm Rotary Actuator

nnnn

Fisher 2052 spring-and-diaphragm rotary actuators are

nnnn

used on rotary-shaft valve bodies for throttling or

nnnn

on-off applications. The 2052 may be used for

nnnn

throttling service with a positioner, or it may be used

nnnn

for on-off service without a positioner. The 2052 has an

nnnn

ISO 5211 mating interface that allows installation to

nnnn

non-Fisher valves. Refer to separate bulletins for valve

nnnn

and positioner information.

Features

nnnn

■ Compact design, smaller actuators- Ensures

nnnn

reduced valve/actuator envelope dimensions

nnnn

leading to greater mounting versatility for both

nnnn

skids and process plants, where space is at a

nnnn

premium.

nnnn

■ Compatible with DVC2000, DVC6200, and

nnnn

DVC6000 digital valve controllers; and 3610J and

nnnn

3620J positioners- The new actuator allows

nnnn

linkage-less feedback, via a contact-less magnetic

nnnn

array, from the lever to the end-mounted DVC2000.

nnnn

Integral window mounting of the DVC6200,

nnnn

DVC6000, 3610J, and 3620J is also available.

nnnn

■ Clamped lever to reduce lost motion- The clamping

nnnn

of the lever onto a splined valve shaft, coupled with

nnnn

the single pivot linkage, reduces lost motion

nnnn

between the actuator and the valve. The typical

nnnn

cumulative deadband for a Fisher rotary control

nnnn

valve assembly results in 0.5% or less variability.

nnnn

■ No bench set required- The new nested spring

nnnn

design requires no bench set. This also simplifies the

nnnn

actuator selection process, see table 3.

nnnn

■ ISO 5211 mounting with optional insert- The

nnnn

actuator can now be mounted directly onto

nnnn

non-spline shafts, such as Square and Double D. This

nnnn

allows the actuator, with its enhanced control, to

nnnn

mount on a wider range of valves conforming to ISO

nnnn

5211.

nnnn

Fisher Control-Disk™ Valve with 2052 Actuator and

nnnn

FIELDVUE™ DVC6200 Digital Valve Controller

nnnn

■ Adjustable travel stops standard with optional

nnnn

lockout feature- Provides the ability to adjust or

nnnn

change the travel range without removing the

nnnn

actuator or the addition of extra parts. The optional

nnnn

lockout feature locks the lever in the spring-fail

nnnn

position.

nnnn

■ Fail-safe mechanism contains no aluminum- All

nnnn

parts in the fail-safe mechanism (made of steel, cast

nnnn

iron, and ductile iron) ensure the actuator will

nnnn

maintain safety integrity in the event of a fire.

nnnn

■ Powder paint as standard- The Emerson Process

nnnn

Management™ powder paint finish offers an

nnnn

excellent corrosion-resistant finish to all external

nnnn

steel and cast iron parts.

nnnn

■ NAMUR VDE/VDI3845 for accessory mounting-

nnnn

Meeting the global standard ensures compatibility

nnnn

for most accessories, enabling quick and easy

nnnn

mounting.

nnnn

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

nnnn

actuator/valve assembly action can be converted

nnnn

from push-down-to-open to push-down-to-close, or

nnnn

vice-versa, without additional parts.

nnnn

■ Declutchable and top-mounted handwheels-

nnnn

Available (except top-mounted not available for size

nnnn

3 actuator).
