Figure 34 HMT318 Ball Valve Assembly Installation
The following numbers refer to Figure 34 above:
1 = Manual press tool
2 = Handle of the ball valve
3 = Probe
4 = Process chamber or pipeline
5 = Groove on the probe indicates the upper adjustment limit
6 = Filter
7 = Ball of the ball valve
8 = Clasp nut
NOTE The probe can be installed in the process through the ball valve assembly
provided that the process pressure is less than 10 bars. This way, the
process does not have to be shut down when installing or removing the
probe. However, if the process is shut down before removing the probe,
the process pressure can be max. 20 bars.
NOTE When measuring temperature dependent quantities make sure that the
temperature at the measurement point is equal to that of the process,
otherwise the reading may be incorrect.
