Two aspects that primarily define operator selection are human factors and economic factors. Another factor influencing the selection of manual operators is the valve’s expected frequency of operation and the physical location of the operation (that is, high in a superstructure or situated in an inhospitable environment), which could also present challenges to personnel.ĭesigners must weigh all of these factors in their decision matrix to receive the most productive yet acceptable selection of how a valve should be operated. A lot of effort and a high number of turns can result in personnel fatigue, safety concerns, excessive time for operation, and the need for multiple personnel. Two concerns considered during the selection of manual operators are the effort required to operate the valve and the number of turns they require. Automated devices, on the other hand, require input energy systems, control systems, additional installation space, and infrastructure for support, operation, and maintenance. Manual operators are simple and inexpensive and require little peripheral planning beyond the installation and orientation of operators in the process line. Opening or closing valves can be completed either by manual input or automated devices driven by various energy sources. Gears are simple machines that use a series of mechanical parts to increase efficiency-the mechanical advantage that the user gains. Manual operators, such as gears require little peripheral planning beyond the installation and orientation of operators in the process line. There are a variety of options to achieve this, including handwheels, levers, gears, and actuators.
