    Rated actuator torques and valve torque requirements are usually conservative. Only a small safety factor is necessary, especially for onoff valves where the main consideration is getting the valve in and out of the seat. The ball valve torque requirement is similar in shape to that of the butterfly valve.

  • Valve actuatorWikipedia

    A valve actuator is the mechanism for opening and closing a valve.Manually operated valves require someone in attendance to adjust them using a direct or geared mechanism attached to the valve stem. Poweroperated actuators, using gas pressure, pressure or electricity, allow a valve to be adjusted remotely, or allow rapid operation of large valves.

    Lead and Zinc Ores Minerals of lead and zinc commonly are rather closely associated in nature; zincfree lead ores and leadfree zinc ores are exceptional rather than common, although there are such. Lead and zinc ores usually contain some silver, but those of the Mississippi Valley region are silverfree. Indeed, leadzinc ores often are commercially valuable chiefly because of their silver
