This extremely compact flow control valve regulates the piston speeds of pneumatic cylinders. The flat design is made possible by the side-mounted adjustment screw, which can be set using an Allen key. The integrated air connection also saves space, facilitating a more compact installation of the pneumatic cylinders. The way the valve is mounted also increases flexibility: It is screwed directly into the cylinder cap via a connecting thread, and can be swiveled through 360°. The design reflects this, thus emphasizing the valve`s principle of operation. As with all Festo products, the color blue represents control elements.
