Fisher 1052 Spring Return Diaphragm Rotary Actuator
Fisher 1052 spring-return diaphragm rotary actuators operate splined shaft rotary valves and are suitable for on/off or throttling service. Designed for easy installation of a broad range of options: limit switches, position indicating switches, positioners, and manual over-rides.
The primary difference between these actuators is that the 1052 actuator has a spring adjuster which means it may be used with or without a positioner, depending on service requirements. The 1051 actuator, in throttling service, is normally equipped with a valve positioner. 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
information concerning option applicability and specifications.
Application Flexibility—Type 1051 and 1052 rotary actuators are available with fail-open or fail-close construction and can be mounted in any of four actuator-valve mounting positions. For mounting positions. These actuators can be mounted on a broad range of Fisher_ valves (style F or G mounting), or used with other equipment (style H or J mounting).
Minimal Dead Band—Single joint linkage with splined and clamped lever minimizes lost motion and improves control accuracy.
Long Service Life—Rugged construction provides stability, corrosion resistance, and
protection from deformation should over-pressurization occur.
Safety—Actuator-valve linkage is completely enclosed, yet the valve packing adjustment remains accessible without removing any parts.For safety during disassembly, spring
compression is controlled on the Type 1051 actuator. The Type 1052 actuator has an externally accessible spring adjuster to relieve spring compression.
|Actuation||Spring-return, Quarter-turn, Rotary|
|Control Type||On/Off, Throttling|
Ball Valve, Butterfly Valve, Eccentric Plug Valve, Triple Offset Valve
Type 1051: For on-off service or for throttling
Type 1052: For on-off service without a positioner or for throttling services with or without
Direct Acting: Increasing loading pressure extends the diaphragm rod out of the spring barrel.
