Rotork delivers fire safety actuation for XRL

A proven reputation for reliability in previous transport tunnel projects has contributed to the selection of Rotork RC scotch-yoke pneumatic actuators for critical safety applications on the Hong Kong Express Rail Link (XRL). The XRL is part of the new 143 kilometre high speed rail connection between Beijing, Guangzhou, Shenzhen and Hong Kong which is designed to reduce the current journey time by 50%. Five hundred high temperature specification RC200 actuators have been ordered by TROX Technik for the operation of fire dampers inside the railway tunnels, meeting stringent safety standards that demand rapid closure in the event of a fire. The actuated fire damper package is able to continue to operate for two hours at a temperature of 250°C to enable smoke control in the event of a fire. Rotork RC200-SRHT series actuators handle this requirement without the use of a fire jacket. Compact dimensions, powerful performance and local support from the Rotork global service network have facilitated their selection for road and rail tunnels around the world. Another recent example is the use of RC200-SRHT actuators for the Istanbul Metro subway network expansion project in Turkey.
