Specification

SEODescription

The FESTO QSL-12 Valve is a compact pneumatic flow control solution featuring a 12mm port size, designed for precise regulation of air flow rates up to 12 L/min. It integrates the QSL-12 Pneumatic Connector for seamless integration with standard 12mm tubing, ensuring leak-free connections. The valve supports direct modular expansion, allowing multiple units to be daisy-chained for scalable system configurations. With a 24V DC operating voltage (10-30V range) and a temperature tolerance of -10°C to +60°C, it suits industrial automation, packaging, and assembly lines. The QSL-12 12mm Flow Control offers adjustable metering via a manual screw mechanism, enabling fine-tuned pressure stabilization. Key advantages include rugged construction, low power consumption, and tool-free installation, though its lack of digital feedback limits compatibility with advanced IoT systems. Communication interfaces like CANopen or PROFINET may require additional modules.
