| Valve maintenance, also pay attention to the first and the transmission of electric water problems. Infiltration of rainwater, especially during the rainy season. First, the transmission or drive shaft cover rust, and second, the winter freeze. Caused by electric valve operation torque is too large, no-load damage to transmission components or super torque motor would jump to protect electric operation can not be achieved. Damage to transmission parts, manual operation can not be. After the action in the ultra-torque protection, also can not switch to manual operation, such as the forced operation, the damage to the internal alloy components.
