Schischek RedRun 25.50 (090.4303) is a powerful linear electric actuator for valves with explosion protection, designed for use in potentially explosive atmospheres with the presence of gases (zone 2) and dust (zone 22). This actuator is characterised by high force (2.5/5.0 kN) and adjustable stroke (20-100 mm), making it ideal for controlling larger industrial valves with a requirement for reliable and safe operation in hazardous environments. It supports both on/off and 3-point control.
