Fisher™ 1052 Size 70 Diaphragm RotaryActuator - 1

Product Bulletin Fisher™ 1052 Size 70 Diaphragm Rotary Actuator Fisher 1052 size 70 spring‐return diaphragm rotary actuators operate splined shaft rotary valves, such as 8580, 8532, 8590, CV500, V500, and Vee‐Ballt (V150, V200 and V300) valves. 1052 actuators are suitable for on‐off service or for throttling service. This actuator is 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 information concerning option applicability and specifications. Features n Application Flexibility-- 1052 rotary actuators are available with fail‐open or fail‐close construction and can be mounted in any of four actuator‐valve mounting positions. See figure 5 for mounting positions. These actuators can be mounted on a broad range of Fisher valves or used with other equipment. Typical Fisher 1052 Actuator with Vee‐Ball Valve and FIELDVUE™ DVC6200 Digital Valve Controller n Minimal Dead Band-- Single joint linkage with splined and clamped lever minimizes lost motion and improves control accuracy. n Long Service Life-- Rugged construction provides stability, corrosion resistance, and protection from deformation should over‐pressurization occur. n Safety-- The 1052 actuator has an externally accessible spring adjuster to relieve spring compression (see figure 1). Actuator‐valve linkage is completely enclosed, yet the valve packing adjustment remains accessible without remov

Fisher™ 1052 Size 70 Diaphragm RotaryActuator - 3

Product Bulletin D104082X012 Positioner: For precise positioning of the valve disk or ball, the actuator should be equipped with a positioner. Under some service conditions, the 1052 actuator may be used successfully in these applications without a positioner. For additional information, contact your Emerson sales office or Local Business Partner with complete service conditions. Adjustable Down‐Travel Stop: Used to limit the actuator stroke in the downward direction (see figure 3). Figure 1.

Product Bulletin Figure 6. Dimensions (also see tables 6, 7 and 8) TOP‐MOUNTED HANDWHEEL ACTUATOR/VALVE BODY MOUNTING DIMENSIONS 1/2‐14 NPT SIZE 70 Installation The actuator is normally positioned vertically in a horizontal pipeline. Four mounting styles and four positions for each style are possible (see figure 5). Due to its weight, the 1052 size 70 actuator must be externally supported if mounted in the horizontal position. When looking in the direction of flow in the pipeline, an actuator is right‐hand mounted when it is on the right side of the pipeline, and an actuator is left‐hand...

Product Bulletin Adjustable Travel Stops Figure 7. Actuator Locking Mechanism Adjustable travel stops (in addition to those shown in figure 3) are available as discussed below. ACTUATOR LEVER As used here, down or downward means in a direction toward the valve shaft and away from the piston and diaphragm. MODIFIED ACTUATOR HOUSING An adjustable down travel stop is installed in a special actuator housing. The assembly consists of a special housing, cap screw, locknut, lever, and rod end bearing. The cap screw can be positioned to limit downward travel of the actuator lever to any rotation...
