Festo LRLL-1/4-QS-10 | G1/4 Meter-Out Flow Control Valve, 10mm OD Tube
Festo LRLL-1/4-QS-10 one-way flow control valve (meter-out). G1/4 female port, QS-10 push-in for 10mm tube, needle adj., for exhaust flow regulation on pneumatic cylinders.

Product Overview

The Festo LRLL-1/4-QS-10​ is a one-way flow control valve (meter-out type)​ from the LRLL series, used to regulate the exhaust (return) flow​ from a double-acting pneumatic cylinder to control retraction speed. It features a G1/4" female threaded port​ for inline installation and a QS-10 push-in connector​ for 10 mm outside-diameter nylon/PU tubing. The valve allows full free-flow in the reverse direction and adjustable throttling in the metered direction via a knurled knob with lock nut.

Key Features

  • Meter-Out (Exhaust) Throttle:​ Installed on the cylinder exhaust port​ — controls rod speed without causing cylinder judder/stick-slip common with meter-in throttling on double-acting cylinders.
  • Push-In Tube Release:​ Quick-connect/disconnect for Ø10 mm tubing — simply push tube in; lift collet to remove. No tools for tubing.
  • Lockable Adjustment:​ Knurled knob with integrated lock nut secures the flow setting against vibration.
  • Free-Flow Check:​ Unrestricted reverse flow ensures no back-pressure builds on the supply side of the cylinder.

Applications

  • Cylinder Speed Control:​ Regulating extend or retract speed of double-acting cylinders (typically meter-out on both ports for independent control).
  • Conveyor & Packaging Machines:​ Fine-tuning actuator velocity on pick-place heads, pushers, and clamps.
  • Retrofit / OEM:​ Direct screw-in replacement on ISO 6432 / ISO 15552 cylinder exhaust ports with G1/4 threads.
Note: For meter-in (supply side throttling), use the GRLL series​ (opposite flow direction). For other tube sizes: QS-6 (Ø6 mm), QS-8 (Ø8 mm), QS-12 (Ø12 mm) are also available in the LRLL-1/4-QS-x family. Always install meter-out for best double-acting cylinder performance unless application specifically requires meter-in.
