Frequently Asked Questions

A manual override is a mechanical feature that allows an operator to manually operate a valve or actuator in the event of power or air supply failure. It ensures safe and reliable control during emergencies or maintenance activities.

Manual override is essential for:

  • Emergency operation during power or air loss
  • Testing or calibration of valves
  • Maintenance or inspection without automation power
  • Safety assurance in critical process applications

It typically involves a handwheel, wrench, or lever mechanism that mechanically engages the actuator’s drive system. When activated, it allows manual rotation or movement of the valve stem to open or close the valve.

Common types include:

  • Handwheel type: Rotary motion to open or close the valve.
  • Wrench type: Operated using a detachable wrench.
  • Declutch lever type: Mechanically disengages the actuator drive before manual operation.
  • Gearbox type: Used for large valves requiring high torque.

Yes. Both pneumatic and electric actuators can be equipped with manual override systems, though their mechanisms differ based on actuator type.

Yes, but with caution. On spring-return actuators, manual operation should be performed against spring tension, or using a mechanical lock to prevent sudden movement.

  • Ensure air/electrical power is isolated.
  • Verify system pressure is vented.
  • Do not force the handwheel beyond valve limits.
  • Follow the torque and direction indicated on the actuator.
  • Wear safety gear when operating under load conditions.

  • Reliable operation during emergencies
  • Increases system safety
  • Allows testing and maintenance without automation
  • Prevents downtime during control failures

Not always, but it is highly recommended for safety-critical applications where valve position control is essential during power loss or system failure.

If a manual override fails, the actuator may not respond manually. In such cases:

  • Do not force the mechanism.
  • Inspect for mechanical jam or gear wear.
  • Contact manufacturer or maintenance personnel for repair.
