When used in conjunction with our KUG-S ball valve shut-offs for measuring devices, KOBOLD sensors for measuring such variables as pressure, temperature or flow can be installed as part of a compact unit in pipe systems. This system allows easy and economical sensor removal for maintenance or replacement without having to drain the pipe system. This shut-off valve features a large ball with a groove that holds the sensor. This design allows sensors of the same length to be installed in valves of different nominal diameters.
