Ưu điểm kỹ thuật quan trọng
-
Seismically-Qualified Architecture: The 1052PSV is built for resilience. Its design replaces standard lightweight components with a fabricated box construction, ensuring that the actuator maintains functional alignment and performance during and after significant seismic acceleration.
-
Enhanced Dual-Spring Thrust: This model incorporates SS129 dual springs mounted within the actuator box. This redundant spring configuration provides the consistent, high-force return necessary for fail-safe operation in safety-related loops.
-
Precision Turnbuckle Adjustment: The actuator features a turnbuckle adjusting mechanism that allows for extremely fine-tuning of the valve’s starting position. This feature simplifies the calibration process and ensures precise alignment between the actuator and the rotary valve shaft.
-
Dynamic Tilting Diaphragm Rod: To minimize side-loading and wear on the diaphragm and bearings, the 1052PSV utilizes a tilting diaphragm rod. This allows the linear motion of the diaphragm to convert smoothly into rotary motion through the lever arm, extending the operational life of the seals.
-
Adjustable Travel Limits: Integrated into the bottom of the fabricated box are adjustable travel limit bolts. These bolts allow operators to mechanically restrict the valve’s open position, providing a physical stop that ensures repeatable and safe flow maximums.
-
Standardized Positioner Integration: Despite its specialized construction, the actuator box is designed to accommodate standard 3610J series positioners. This ensures compatibility with existing Fisher instrumentation and control ecosystems
