Notes upon Torques:
The values specified are guide values and apply to lubricated nuts and bolts.
With valves that have been in service for a long time and already are worn-out on the sealing surface or
in the case of gaseous medium , where leakage is detected under high pressure, the tightening torques
can be increased by max. 40 %.
