PERCON is the pneumatic actuator we have developed in house. This actuator system has proven its reliability, particularly in safety-sensitive areas such as nuclear technology. These actuator offer multiple advantages over electrical actuators. Firstly, no explosion protection is required as no electrics are used. Secondly, the valve can assume a pre-defined position if the control air supply is interrupted, but it is still possible to control it manually afterwards. Plus, PERCON boasts a simple design and robust components, which means the service life is long whilst the maintenance costs are low.
