Operating Torques |
The actual amount of torque required to operate a valve is dependent upon many variables, such as: line pressure, temperature, type of fluid, frequency of position.
The following table is based on average breakaway torque requirements for a valve handling a clean, particle-free liquid such as water. the following charts include a safety allowance for service conditions. The torque figures listed should be further adjusted for special serviceconditions. For fluids with high solids or abrasive content, consult factory for recommendations.
| Size | Torque (ft. lbs.) |
|---|---|
| 1/2" | 10 |
| 3/4" | 10 |
| 1" | 10 |
| 1-1/2" | 20 |
| 2" | 35 |
| 2-1/2" | 48 |
| 3" | 62 |
| 4" | 130 |
