D100089X012 Type 1051 and 1052 Diaphragm Rotary Actuators The Type 1051 and 1052 spring-return diaphragm rotary actuators (figure 1) operate splined shaft rotary valves, such as the e disc R (Type 8510B and 8560), Types 7600, 8532 and 9500, and Vee-Ballr (Design V150, V200 and V300) valves. Types 1051 and 1052 actuators are both suitable for on-off service or for throttling service. The primary difference between these actuators is that the Type 1052 actuator has a spring adjuster (see figure 2) which means it may be used with or without a positioner, depending on ser- vice requirements. The Type 1051 actuator, in throt- tling service, is normally equipped with a valve posi- tioner. Refer to separate bulletins for valve and positioner information. Both actuator types are designed for easy installation of a broad range of options: limit switches, position indicating switches, positioners, and manual over- rides. Option applicability varies with actuator size. Refer to the specifications table and table 4 for in- formation concerning option applicability and specifica- tions. Figure 1.

Type 1051 and 1052 Diaphragm Rotary ActuatorsThe Type 1051 and 1052 spring-return diaphragmrotary actuators (figure 1) operate splined shaft rotaryvalves, such as the edisc�
(Type 8510B and 8560),Types 7600, 8532 and 9500, and Vee-Ball� (DesignV150, V200 and V300) valves. Types 1051 and 1052actuators are both suitable for on-off service or forthrottling service. The primary difference betweenthese actuators is that the Type 1052 actuator has aspring adjuster (see figure 2) which means it may beused with or without a positioner, depending on ser-vice requirements. The Type 1051 actuator, in throt-
tling service, is normally equipped with a valve posi-tioner. Refer to separate bulletins for valve andpositioner information.
Both actuator types are designed for easy installationof a broad range of options: limit switches, positionindicating switches, positioners, and manual over-rides. Option applicability varies with actuator size.Refer to the specifications table and table 4 for in-formation concerning option applicability and specifica-tions.
Figure 1. Type 1052 Actuator with Vee-Ball Valve and DVC5020 Positioner
� Application Flexibility—Type 1051 and 1052rotary actuators are available with fail-open or fail-closed construction and can be mounted in any of fouractuator-valve mounting positions. See figure 8 formounting positions. These actuators can be mountedon a broad range of Fisher Controls valves (style F orG mounting), or used with other equipment (style H orJ mounting).
� Minimal Dead Band—Single joint linkage withsplined and clamped lever minimizes lost motion andimproves control accuracy.
� Longer Service Life—Rugged construction pro-vides stability, corrosion resistance, and protectionfrom deformation should over-pressurization occur.
� Safety—Actuator-valve linkage is completely en-closed, yet the valve packing adjustment remains ac-cessible without removing any parts (see figures 3 and4). For safety during disassembly, spring compressionis controlled on the Type 1051 actuator. The Type1052 actuator has an externally accessible spring ad-juster to relieve spring compression (see figure 2).
Options
Top-Mounted Handwheel: For infrequent use as amanual actuator or for use as an adjustable up travelstop (see figure 7). For repeated or daily manual op-
eration, the unit should be equipped with a declutch-able handwheel actuator.
Declutchable Handwheel Actuator: A side-mountedmanual actuator can be used to provide on-site controland to provide override capabilities. Not available forsize 20 actuators. See Bulletin 61.8:1078 for hand-wheel actuator specifications.
Limit Switches: � Micro-Switch or NAMCO switchesfor one or two single-pole, double-throw contacts, or� GO proximity switches for one or two single-pole,double-throw contacts are available (see figure 6).Proximity switches are not available for Type 1052size 70 actuators. See separate bulletins for limitswitch information.
Position Indicating Switch: Type 304 switch for onethrough six single pole, double throw switch contactsare available. See separate bulletin for position indicat-ing switch information.
Positioner: For precise positioning of the valve disk orball, the actuator should be equipped with a positioner.Under some service conditions, the Type 1052 actua-tor may be used successfully in these applicationswithout a positioner. For additional information, contactyour Fisher Controls sales office with complete serviceconditions.
Adjustable Down-Travel Stop: Used to limit the ac-tuator stroke in the downward direction (see figures 5and 6). Not available for size 20 and size 33 actuators.
Adjustable Up-Travel Stop: Used to limit the actuatorstroke in the upward direction (see figures 5 and 6).Though these assemblies may be installed on the size20 and 33 actuators, they are not necessary for stan-dard operation because the size 20 and 33 actuatorshave integral travel stops.
Actuator Locking Mechanism: For size 33 actuators(figure 9) and size 40, 60, and 70 actuators (figure 10),an actuator locking mechanism is available. It can beused to keep the actuator in a locked position (thesame as the spring-fail position) during maintenance.The padlock is not furnished by Fisher Controls, andthe mechanism requires a modified actuator housing.
Pipe Away Vent: Some applications use natural gasor other hazardous gases as a supply pressure to theactuator. These applications sometimes require theactuator housing to be vented reducing the accumula-tion of gases. For new constructions and retrofit kitinformation, contact the sales office with complete ser-vice conditions.

Installation
The actuator is normally positioned vertically in a hori-zontal pipeline. Four mounting styles and four posi-tions for each style are possible (see figure 8). Due toits weight, the Type 1052 size 70 actuator must be ex-ternally supported if mounted in the horizontal position.
When looking in the direction of flow in the pipeline, anactuator is right-hand mounted when it is on the rightside of the pipeline, and an actuator is left-handmounted when it is mounted on the left side of thepipeline.
By Fisher Controls definition, forward flow is into theface side of the disk or ball, and reverse flow is into thehub side of the disk or ball.
Dimensions for both actuator types are shown in figure11. These dimensions should be used in conjunction

with the mounting positions shown in figure 8. Makeclearance considerations before mounting the actuatorto determine the most suitable mounting position.
Adjustable Travel Stops
Adjustable travel stops (in addition to those shown infigure 5) are available as discussed below.
As used here, down or downward means in a directiontoward the valve shaft and away from the piston anddiaphragm.
An adjustable down travel stop for Type 1051 (size 40and 60) and Type 1052 (size 30, 40, 60, and 70) isinstalled in a special actuator housing. The assemblyconsists of a special housing, cap screw, locknut, le-ver, and rod end bearing. The cap screw can be posi-tioned to limit downward travel of the actuator lever toany rotation between 0 and 90 degrees.
The locking mechanism shown in figures 9 and 10 isnot to be used as a travel stop. Please specify an ad-justable travel stop assembly instead.
