The undirectional flow controllers are equipped with M5, G1/8 and G1/4 ports, each of which is available with two different types of adjustment (see diagrams). They are used mainly for controlling the speed of cylinders. They may be mounted on control panels or cylinders, as required. Bidirectional controllers are also available with the same bodies, but suitably modified.
