Siemens Building Technology 426855108 Crank Assembly
The Siemens 426855108 Crank Assembly is a mandatory field-service component designed for the manual override of Siemens SKB and SKC series electro-hydraulic actuators. Essential for commissioning and emergency positioning, this manual crank handle allows technicians to precisely adjust valve positioning during power failures or system maintenance. Built for durability in demanding mechanical rooms, the 426855108 ensures the stroke of SKB62 and SKC62 actuators can be managed without active power. Its robust drive interface is engineered to withstand the high torque requirements of large-bore globe valve actuators, providing a mechanical failsafe for the Flowrite and OpenAir product lines. When replacing lost or damaged assemblies, using this genuine Siemens HVAC actuator part ensures correct fitment and prevents damage to the internal gear train of the electronic actuator. This assembly is a critical tool for any commercial HVAC contractor managing high-pressure steam or chilled water systems requiring manual valve override capabilities.
Key Benefits:
- Direct Compatibility: Engineered specifically for the Siemens SKB62, SKC62, and SKB/SKC 82 series electro-hydraulic valve actuators.
- Mechanical Precision: Provides tactile feedback during manual operation for accurate valve stroke adjustment.
- Emergency Readiness: Essential for maintaining system control during power outages or controller communication failures.
- Field Durability: High-strength construction designed for repeated use in high-torque HVAC valve automation applications.
Common Technical Questions:
- Can I use this crank on the SKD series actuators? No, this assembly is sized specifically for the larger SKB and SKC actuator variants; the SKD series uses a different manual override mechanism.
- Does this part remain attached to the actuator during normal operation? While it can be stored on the unit, it is often kept in a service kit or mounted nearby to prevent unauthorized manual interference with BMS control signals.
- What is the primary function of the 426855108? It is used to manually drive the actuator to the open or closed position for valve commissioning or troubleshooting.
