Quality features of pneumatic part-turn actuators for valve automation

To operate valves from a distance, whether in automated systems or not, designing engineers have a few actuation options available. Ball, butterfly and other so called quarter turn valves belong, due to material developments, for decades to the most applied valve types in particular in open-close function. And without doubt the rack and pinion, twin piston, pneumatic, mainly quarter turn, actuator is the favourite applied product. There are many reasons why this type of actuator is at pole position.
