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 operation.
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 service conditions. For fluids with high solids or abrasive content, consult factory for recommendations.
