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