Critical Technical Advantages
-
Compact Footprint and Versatile Mounting: The 2052 features a reduced valve/actuator envelope, significantly decreasing its physical dimensions. This allows for greater installation flexibility in tight spaces and makes it easier to integrate into modular skid designs.
-
Minimized Lost Motion: Accuracy is enhanced by clamping the lever directly onto a splined valve shaft. Combined with a single pivot linkage, this design reduces mechanical play and lost motion, ensuring the actuator’s movement is precisely translated to the valve disc or ball.
-
Innovative Nesting Spring Design: The 2052 utilizes a nested spring configuration that requires no bench set. This simplifies the setup process and ensures consistent performance without the need for complex calibration during installation.
-
Linkage-less Digital Feedback: This actuator supports linkage-less position feedback through a contact-less magnetic array. By removing physical linkages between the positioner and the actuator, the system eliminates wear and tear while improving the reliability of the control signal.
-
Field-Adjustable Travel and Action: The 2052 offers industry-leading flexibility with the ability to adjust the travel range by 30 degrees in either direction without removing the actuator. Furthermore, the assembly can be converted from push-down-to-open to push-down-to-close without requiring additional parts.
-
Fire-Safe Integrity: All critical components in the fail-safe mechanism are constructed from steel, cast iron, and ductile iron. This robust material selection ensures that the actuator maintains its safety integrity and fail-safe position even in the event of a fire.
