The rotary actuators play an important safety role in the Turkish subway.
ロトルクジャパン
Rotolock has installed over 150 RC200 pneumatic actuators in the fire dampers' valves of the Turkish subway. (Note: Fire dampers are safety products installed inside railway tunnels to prevent the spread of flames and smoke, closing during a fire to prevent flames and smoke from reaching the railway tunnel.) The RC200 is a compact pneumatic actuator equipped with a Scotch-Yoke mechanism, performing ESD or isolation functions. It was chosen for its fast operating speed and long-term use with minimal maintenance, utilizing a spring-return design. The actuators in the RC range can operate normally even in high-temperature environments ranging from 0 °C to +150 °C. In this case, a high-temperature model capable of withstanding 250 °C for 2 hours and an additional hour at 400 °C was selected. The RC pneumatic actuators operate at such high temperatures without affecting the exterior fireproof coating. This actuator has obtained ATEX 2014/34/EU certification.
