QWL Dual-Drive Manual Valve Gearbox
The QWL dual-drive manual valve gearbox is a reference for applications requiring a defined main and backup drive arrangement. Send the operating requirements and mounting drawing so the supplied configuration can be confirmed.
TECHNICAL DETAILS
QWL dual-drive gearbox selection details
Review the model, material and connection before confirming your component.
| Component | QWL- dual-drive manual gearbox |
|---|---|
| Manufacture | To the selected reference, drawing or sample |
| Material & finish | Confirmed for the requested component |
| Dimensions | Please provide a dimensioned drawing |
| Order requirements | Quantity, destination and inspection requirements |
Published model data is provided for reference. Confirm dimensions, units, material and operating limits against your approved drawing before ordering.
Describe both drive arrangements
Show how the gearbox connects to the valve and how each input is intended to operate. Confirm the primary drive, backup operation, input orientation and available installation space for the selected configuration.
Provide the operating requirements
Include valve type, required operating torque, travel and preferred reduction ratio. A model name does not establish the required output capability; the final selection needs the valve and installation requirements.
Review mounting and sealing
Supply the flange, bolt pattern and drive-opening dimensions. The original listing describes a multi-labyrinth seal design, but it does not establish a specific enclosure or immersion rating. State the environment and required protection for review.
Compare the required function
If the requirement is manual operation with position signalling, see the XWL-R gearbox with signal feedback. For a QWL inquiry, attach the mounting drawing and state sample and batch quantities.
