high pressure actuators
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.
