Valves from Festo are divided into pneumatic, electric (solenoid valves), mechanical or manually actuated directional valves, that, e.g. can be used for the actuation of pneumatic cylinders, flow regulation and pressure regulation valves (mechanically actuated) with which a manually set pressure or flow is regulated, proportional valves, that electronically regulate the pressure or flow, 2/2-directional process valves as solenoid valves, angled poppet valve or (pneumatic actuated) ball valve and pneumatic control elements, such as counters, timers or two-handed control blocks. Logic valves also belong to the blocking valves along with the manually actuated valves.
