Safety Note

Even though there are torque safety factors built into the automated ball valve packages, actual service conditions must also be considered when selecting the proper product for the appropriate application.

Severe service conditions such as dirty water, dirty air, all slurries, raw sewage water, oils, and other viscous fluids can have a dramatic affect in raising the torque requirements of ball valves as much as 75% and therefore larger actuators may be required. Please consult JME when dealing with these types of applications.
