Note:
1. Torque charts shown are a guide to running torques
for general service applications. Under same conditions
floating ball designs may require higher breakaway torques
than shown. Actuators selected should provide torques
at least as high or higher than values shown. (Consult
factory for assistance.)
2.
Torque values shown are based on clean fluids. For other
conditions:
- reduce
by 10% for high lubricity oils
- increase
by 10% for dry gases
- increase
by 40% for fluids with solids or abrasive contents
3.
Consult factory for special service applications, i.e.
metal to metal seals, cryogenic, high temperature, etc.
4.
Consult factory for torque values on 10" and larger
valves.
