Product Description

The FESTO QSL-4H valve is a high-performance pneumatic component designed for rapid exhaust applications in industrial automation systems. This Quick exhaust valve QSL-4H operates within a wide pressure range of 0.15–1.0 MPa and temperature limits of -20°C to +80°C, ensuring reliability in harsh environments. It features two standard 1/8" pneumatic ports for direct integration with actuators, cylinders, or other pneumatic modules, enabling swift air release to optimize cycle times. Ideal for manufacturing, packaging, and assembly lines, the QSL-4H valve excels in reducing response delays with its low-flow resistance design. Key advantages include compact size, corrosion-resistant housing, and maintenance-free operation, though it lacks electronic interfaces or adjustable exhaust settings. The valve supports G1/8 or NPT threaded connections, ensuring compatibility with most pneumatic systems. Its lightweight construction (approx. 0.05 kg) and IP65-rated casing make it suitable for space-constrained installations demanding fast, reliable exhaust functions.
