Critical Technical Advantages
-
Optimized Thrust for Medium-Duty Service: Depending on the specific configuration, the 656 can produce maximum thrusts of up to 5.3 kN (1,200 lbf). This makes it an ideal solution for balancing power and precision in applications that do not require the massive force of larger piston actuators.
-
Flexible Bracket and Plate Mounting: The actuator base features four tapped holes, providing the versatility to utilize either bracket or plate mounting. This feature is particularly valuable for retrofitting the 656 onto existing dampers, louvers, or non-standard valve equipment in the field.
-
Precise Stroke Range: With available strokes up to 105 mm (4 1/8 inches), the 656 accommodates a broad range of travel requirements. This adaptability ensures that the actuator can fully open or close various types of airflow control mechanisms and rotary-to-linear linkages.
-
Rugged Industrial Durability: Constructed with a heavy-duty yoke and casings, the 656 is built to withstand mechanical vibration and corrosive atmospheric conditions. Its robust frame provides the stability necessary to maintain accurate positioning over a long service life.
-
Comprehensive Spring Selection: To ensure a perfect match for your specific control logic, a wide variety of spring rates is available. This allows for precise calibration of the actuator to meet the unique resistance and pressure profiles of your equipment.
-
Reliable Manual Override: The 656 can be equipped with an optional top-mounted handwheel. This allows operators to manually position the actuator during commissioning, maintenance, or in the event of a pneumatic supply failure, enhancing overall system safety.
