The Limitorque LDG Direct Gas powered scotch yoke actuator series is specifically designed to be operated by high pressure natural gas, or any other high pressure pneumatic fluid up to a maximum of 105 barg (1500 psig). LDG actuators are ideal for pipeline applications where no external sources of motive power are present and provide a robust heavy duty design and long service life with industry leading maintenance intervals. This makes them the actuator of choice for installation in remote or unmanned facilities.
