Festo One-way Flow Control Exhaust Valve Female Inlet Male Outlet GRLA-1/8-QS-8-MF-D, 1 bar, Polyamide/Metal, 537076

Festo GRLA-1/8-QS-8-MF-D is a high-performance one-way flow control exhaust valve engineered to provide precise control over pneumatic actuator speed and exhaust air regulation. Built with advanced materials including polyamide, stainless steel, die cast zinc, nickel-plated brass, and reinforced aluminum alloy, the valve ensures long-term reliability and performance in harsh industrial environments.

The GRLA-1/8-QS-8-MF-D is equipped with a female inlet and male outlet, supporting straightforward connection to standard pneumatic circuits. Its integrated QS push-in fitting offers quick installation and the captive seals maintain secure, leak-free operation even during rotation or swiveling through the full 360° axis.

Designed for manual actuation, the valve allows users to adjust flow settings via screwdriver slot operations, catering to slow, medium, or fast piston movement requirements. With a maximum operating pressure of 1 bar and operating temperature from -10°C up to 150°C, it delivers robust performance across a broad range of industrial needs.

Lubrication operation is possible, and the standard nominal flow rate in controlled direction is 475 liters per minute, making the valve suitable for use in rapid or precise pneumatic control tasks. Its threaded mounting style with external (male) thread simplifies installation and removal.

Typical industrial use cases include automated manufacturing lines, material handling machinery, process control systems, robotics, and pneumatic equipment requiring regulated actuator speed or exhaust air management.

Reliable one-way flow control for effective pneumatic speed and exhaust regulation. Rugged multi-material construction for durability and corrosion resistance. Easy installation with integrated QS push-in fittings and captive seals.

Manual adjustment for custom piston movement requirements. Operating range suitable for industrial, commercial, and laboratory environments. RoHS and Germanischer Lloyd standards-approved for quality and safety assurance.
