Smart-Hose Technologies” Smart-Hose safety system connects a coated cable within the hose bore to the valve plungers, wedges, or flappers at hose endpoints. Acting as a compression spring, the cable will hold valves open when conditions are normal. The instant thrust is eliminated due to coupling ejection, hose stretching, or hose separation, both valves seat themselves, stopping all flow in either direction. The technology is a good fit for applications in chemical processing, offshore drilling, agriculture, petroleum refining, rail, highway or ocean-going transportation, pharmaceuticals, and food processing. The hose technology has received U.S. Department of Transportation exemption for railcar unloading, tank car loading, and the governmental mandate requiring a passive device for the loading and unloading of compressed gas cargo tankers.
