Description
The Festo GRLA-1/4-QS-6-RS-D is a high-performance one-way flow control valve designed to precisely regulate exhaust air flow while preventing backflow, enhancing control in pneumatic actuators and systems. This model features a QS-6 push-in fitting on one end and a G¼ threaded connection on the other, making it easy to install into a wide variety of industrial setups.
With a knurled adjustment screw, users can make fine flow rate adjustments without tools. The valve handles standard flow rates up to 600 l/min in the controlled direction and up to 680 l/min in the non-return direction at 6 bar, making it suitable for demanding automation environments.
Its rugged construction includes anodized aluminum components, stainless steel adjusting screw, and NBR seals, ensuring durability under harsh industrial conditions. Certified for cleanroom use (ISO Class 4) and compliant with RoHS and VDMA24364-B1/B2-L standards, this valve is both safe and versatile.
