Festo One-Way Flow Controller Exhaust Valve Brass Anodised Aluminium Alloy ISO 1179-1 ISO 228-1 Threaded GRLA-3/8-QS-6-D

Festo GRLA-3/8-QS-6-D is a precision one-way flow controller exhaust valve designed for use in pneumatic systems to regulate and control exhaust air flow speed effectively. It features threaded inlet and outlet connections conforming to ISO 1179-1 and ISO 228-1 standards, promoting compatibility with various pneumatic installations.

The control valve comprises a slotted head screw adjusting element and a robust threaded plug made from wrought aluminium alloy with a brass adjusting screw for precise flow regulation. Its construction includes a durable combination of brass, anodised wrought aluminium alloy, polyamide-reinforced polymers, nitrile rubber (NBR), nickel plated brass, high alloy stainless steel, fluoroelastomer (FPM), and die cast zinc components.

This valve ensures piston speed regulation during advance and return strokes with one-way flow control functionality, making it ideal for pneumatic drivers. The QS push-in fittings and captive seals, combined with its robust metal design, allow reliable and efficient installation, including rotation or swiveling through a full 360° axis, facilitating flexible piping layouts.

Designed for manual actuation via a screwdriver slot, it supports a standard nominal flow rate of 495 l/min and operates within a maximum pressure of 1 bar and a wide temperature range from -10°C to 150°C. The valve installs using threaded mounting compatible with a nominal tightening torque of 10 Nm and can be assembled in any position without affecting performance.

Certified to meet RoHS, ISO 8573-1:2010 (7:4:4), and Germanischer Lloyd standards, the GRLA-3/8-QS-6-D assures compliance with environmental and quality regulations. Originating from Germany, it is suitable for various industrial applications requiring precise pneumatic flow control, including manufacturing automation and fluid power systems.
