Exhaust air flow control valve with G1/8 thread and 6mm push-in port. Delivers 165 L/min nominal flow for precise pneumatic cylinder speed regulation.
The Festo VFOE-LE-T-G18-Q6 (Part No. 8068726) is a precision exhaust air one-way flow control valve engineered for industrial pneumatic systems. Featuring a G1/8 threaded connection and a 6mm push-in port (QS-6), it allows accurate regulation of piston speeds in pneumatic cylinders. The valve incorporates a robust PBT housing, a galvanized steel threaded bolt, and reliable HNBR/NBR dynamic and static seals. A color-coded manual rotary knob with a secure detent mechanism ensures tool-free, vibration-resistant flow adjustments. Compliant with ISO 14644-1 Class 4 cleanroom standards and VDMA24364 zone III LABS conformity, it is highly suitable for demanding industrial and precision assembly environments.

Utilizes the 165 L/min controlled flow rate and manual rotary knob to precisely adjust the exhaust air, dictating the extension or retraction speed of pneumatic cylinders in automated assembly lines.
Prevents abrupt, jarring actuator movements that could damage delicate parts or mechanical stops during automated indexing or positioning tasks.
Integrates directly into semiconductor or medical device manufacturing machinery requiring ISO Class 4 cleanroom compatibility. The PBT housing and NBR/HNBR seals prevent particulate contamination while controlling pneumatic drives.
Ensures accurate pneumatic control without shedding particulates or violating strict cleanroom standard requirements, maintaining production environment purity.
Mounts directly onto robotic tooling where physical space is extremely limited. The compact, 360-degree swiveling valve allows 6mm tubing to route cleanly, while the tool-free detent knob enables fast, lockable speed tuning.
Eliminates the need for bulky external manifolds to tune pneumatic grippers or linear slides, fitting compactly right at the point of actuation.
