Thread Content

3. Fault phenomenon of frequent torque protection tripping: The torque protection activates during the switching process, causing the valve to stop midway. Detection method: 1. The torque set value is too low ； 2. Excessive medium pressure at the valve, with scaling causing the valve core to get stuck ； 3. Bent valve stem, overly tight packing, corroded bearings ； 4. Torque sensor/torque switch drift and damage. Solution: 1. Adjust the torque setting appropriately within the rated range ； 2. Remove scale and debris from the valve body, and manually turn the valve to ensure there is no sticking ； 3. Straighten the valve stem, replace the bearings, and adjust the packing tightness appropriately ； 4. Replace the torque switch or torque detection module.
