Procedural control of valve operation using mechanical valve interlocks and activity management systems.
Flexi-Drive™ remote valve actuators
Remote valve actuators are a remote operating system for valves and other handwheel-operated devices.
In a hazardous area, below water, in a confined space, in a pit, where noxious fugitive emissions prevail or just plain out of reach, Flexi-Drive® is the answer. Flexi-Drive® is a very versatile product consisting of two stations, joined by a unique patented linear drive cable.
This equipment enables valves and other wheel operated devices in remote, hard-to-reach or hazardous locations to be operated easily from a conveniently located handwheel.
Developed originally for use by the US Navy to operate valves in inaccessible locations on board ships, Flexi-Drive® can now be applied to any conventional wheel-operated valve/device, in oil, gas & chemical processing plants. It is suitable for underwater applications and will function reliably in all climatic conditions.
The cable system can transmit drive to a valve up to 60 metres from the operator station. The flexible cable system facilitates up to 540° of bends in the cable run.
