QDifference between self-sealing and non-self-sealing pneumatic modules

- Self-sealing: Internal valves close automatically upon separation to prevent air/vacuum leakage, ideal for pressure-maintaining scenarios
- Non-self-sealing: Open interface with lower flow resistance and larger flow rate; cut off air supply before separation to avoid air ejection

- Non-self-sealing: Open interface with lower flow resistance and larger flow rate; cut off air supply before separation to avoid air ejection
QHigh-flow and vacuum compatible pneumatic modules

Q11 straight-through low-resistance pneumatic module with 8mm nominal diameter supports max 1.0MPa positive pressure and 90% vacuum environment, ideal for large vacuum sucker gripping applications.

QModule expansion without overall replacement

No need for full replacement. QT-650S, QT-2060 and other models adopt circumferential standardized module layout with reserved expansion interfaces. Users only need to add required pneumatic or communication modules on vacant mounting positions during production line upgrading to protect initial investment.
