Apr 23, 2018 . The manual operator is usually placed in a mid-stroke position. Even though a manual on-off Valve is being used for basic throttling, it is not considered a control Valve because it is not part of a process loop, which requires some type of self-actuation as well as input from a controlling device to the Valve. Manual Valve Classifications. Manual Valves are usually classified into four types, depending …

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. Power-operated actuators, using gas pressure, hydraulic pressure or electricity, allow a Valve to be adjusted remotely, or allow rapid operation of large Valves. Power-operated Valve actuators may be the final elements of an automatic control loop which automatically regulates some flow, level or ot
Gear operated Valves are the more complex of the two manual operators. Their installation and operation usually requires more effort than lever operated Valves. Most gear operated Valves have worm gears that make them easier to open and close. This means that the majority of gear operated Valves can fully open or close with only a few turns.
Hydraulic actuators are most commonly utilized to operate butterfly Valves that require a rotation of less than 360 degrees within the pipe to provide the fluid level control. The hydraulic Valve actuator converts electrical signals into fluid pressure within the hydraulic cylinder to provide the movement.
