Festo GRLA Series Flow Controller Exhaust Valve Threaded ISO 1179-1 and ISO 228-1, 1 bar Pressure, -10°C to GRLA-1/8-QS-4-D

Festo GRLA-1/8-QS-4-D Flow Controller Exhaust Valve is designed for precise pneumatic flow regulation in industrial and manufacturing applications. Featuring threaded ISO 1179-1 and ISO 228-1 connection standards, it ensures a secure, leak-free fit with compatible pneumatic components. The valve supports operating pressures from 0.2 bar to 1 bar and a nominal flow rate of approximately 160 L/min, making it suitable for speed regulation in piston drivers and other pressurized pneumatic equipment.

Constructed with durable materials such as nickel plated brass, anodised wrought aluminium alloy, stainless steel, and elastomer seals (FPM and NBR), this valve withstands challenging industrial environments. It operates reliably across a wide temperature range from -10°C to 150°C, thereby accommodating various heating and cooling requirements.

The valve's 4 mm push-in fitting swivels 360°, facilitating easy access and installation flexibility in complex assemblies. Flow rate adjustments can be performed with a simple slotted screwdriver, offering user-friendly control without specialized tools. Its suitability for lubricated compressed air further enhances versatility for diverse pneumatic tasks.

This component meets stringent quality and safety standards, including Germanischer Lloyd certification and ISO 8573-1:2010 (7:4:4), and complies with RoHS directives. The device is not certified for hazardous areas but excels in standard industrial settings.

Ideal use cases include pharmaceutical production facilities, food and beverage manufacturing plants, and printing presses where consistent, safe, and stable pneumatic control is essential.

Flow rate is adjustable by hand using a simple slotted screwdriver. 360° swivel fitting allows easy access and installation flexibility.
