Wherever hoses are used to move industrial fluids or gases, the potential for spills or catastrophic leaks is never more than seconds away. The new hose assembly protects personnel by automatically shutting off flow in both directions the instant a hose failure taks place. The safety system connects a coated cable within the hose bore to the valve plungers, wedges or flappers at hose end points. 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.
