A major utility approached Superbolt about using their Multi-Jackbolt Tensioners to reduce down-time on their large Ball Valve. Previously they used a hydraulic bolting method. The estiamted time savings was 2-3 days with the Superbolt Tensioners, and an estimated 5 million dollars (US) was saved...

One of the key advantages of a ball valve over older types (such as conical plug valves, which are the traditional valve used for gas meter sets) is that the ball valve seals absolutely bubble-tight without any sealant or lubricant being required. The reason for this is that the geometry of a ball...

RuB ball valve styles which use teflon stem seals (s.40, 42, 70, and 92) are rated at 150 psi WSP (Working Steam Pressure). But our valve styles which have FPM (like DuPont Viton (R)) stem seals (the s64 or s95 for example) cannot be consistently satisfactory at 150 WSP without some restrictions...
