重要な技術的利点
-
Flexible Mounting and Failsafe Action: The 1052 is available in both fail-open and fail-close constructions, providing essential safety for critical process loops. It can be mounted in any of four distinct actuator/valve positions, offering high adaptability for integration with various Fisher valves or third-party equipment.
-
High-Precision Control Accuracy: To ensure superior throttling performance, the actuator utilizes a single-joint linkage combined with a splined and clamped lever. This robust mechanical connection minimizes lost motion between the actuator and the valve shaft, resulting in high-fidelity positioning.
-
Rugged and Safe Construction: Built for demanding industrial environments, the 1052 features a heavy-duty design that provides exceptional stability and corrosion resistance. The casing is engineered to provide protection from deformation even in the unlikely event of over-pressurization.
-
Simplified Maintenance and Safety: The actuator includes an externally accessible spring adjuster, allowing technicians to safely relieve spring compression during maintenance. Furthermore, while the actuator/valve linkage is completely enclosed for safety, the valve packing remains accessible for adjustment without the need to remove any components.
