2052 Actuator Features
Compact design, smaller actuators– Ensures
reduced valve/actuator envelope dimensions
leading to greater mounting versatility for both
skidsandprocessplants,wherespaceisata
premium.
Compatible with DVC6200 and DVC2000 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
window-mounted DVC6200 or end-mounted
DVC2000. Integral window mounting of the 3610J
and 3620J is also available.
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 i n 0.5% or less
variability.
No bench set required– The new nested spring
design requires no bench set. This also simplifies t he
actuator selection process, see bulletin 61.1:2052,
D103295X012.
ISO5211mountingwithoptionalinsertThe
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.
Adjustable travel stops standard with optional
lockout feature– Provides the ability to adjust or
change the travel range without removing the
actuator or the addition of extra parts. The optional
lockout feature locks the lever in the spring-fail
position.
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.
Powder paint as standard– The Emerson Process
Management powder paint finish offers an excellent
corrosion-resistant finish to all external steel and
cast iron parts.
NAMUR VDE/VDI 3845 for accessory mounting
Meeting the global standard ensures compatibility
for most accessories, enabling quick and easy
mounting.
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.
Declutchable and top-mounted handwheels–
Available (except top-mounted not available for size
3actuator).
