Product Description

The Festo QSF valve model QSF-1/4-12-B is a compact 2-position pneumatic solenoid designed for precise flow control in automation systems. With 1/4" port size and 12V DC voltage, this normally closed (B-type) solenoid supports direct integration into modular pneumatic setups, featuring a Cv flow rate of 0.5 for optimized performance. It operates within 10-30°C and 0.1-10 bar pressure, compatible with IO-Link for digital communication. The Festo pneumatic solenoid includes a DIN-compatible plug connector and achieves IP65 protection for industrial durability. Ideal for manufacturing, packaging, and assembly lines, its low power consumption (1.8W) and fast switching (<10ms) ensure reliable actuation. Though lacking onboard diagnostics, its maintenance-free design excels in repetitive operations. The valve interfaces seamlessly with Festo CPX/MPA platforms via standard M5 electrical connections.
