重要な技術的利点
-
Seamless El-O-Matic Integration: The 1080 is engineered to correspond directly with the sizing of the 1035 actuator series. This eliminates complex torque calculations during the procurement process; once the 1035 power actuator size is determined, the matching 1080 size is automatically identified.
-
Simplified Direct Mounting: The 1080 mounts directly to the 1035 actuator housing. This integrated design approach simplifies the installation process and removes the need for additional brackets, yokes, or coupling hardware, resulting in a cleaner and more stable assembly.
-
Flexible Engagement Mechanism: Featuring a lever-operated eccentric bearing support on the input shaft, the 1080 allows the worm gear to engage the sector at any point in the valve’s rotation. This means manual control can be established instantly, regardless of the valve’s current stroke position.
-
Enhanced Safety Locking: To prevent accidental engagement or disengagement, the actuator utilizes a spring-loaded pin mechanism. This pin must be manually released before the lever can be moved, providing a physical safeguard against inadvertent operation during active automated cycles.
-
Continuous Position Awareness: The actuator is designed to maintain accurate travel indication. Because the feedback components remain synchronized with the valve shaft, the operator can see the exact valve position whether the unit is in manual or power mode.
-
Integrated Mechanical Stop-Pins: Built-in stop-pins provide a rigid mechanical limit for the manual travel. This protects the valve and the primary actuator from damage caused by over-rotation during emergency manual operation.
