Metso has released Nelprof 6 valve sizing software. The new version extends earlier Nelprof versions with two new calculation modules, which enable the selection of intelligent automated on/off valves and emergency valves.
Special safety requirements, such as an actuator-sizing safety factor or a complete valve-assembly safety-integrity level, can be evaluated with the tools in the program.
Now Nelprof 6 can be used to select all Metso’s automated on/off and emergency valves. Performance analysis, which has been one of the value-adding features in the control-valve sizing tool since 1980s, can be used to study valve controllability in a closed control loop. The module also includes multiphase flow sizing as well as noise and cavitation prediction analysis.
This on/off calculation tool allows the selection of all Metso metal- and soft-seated on/off valves with advanced actuator sizing, including adjustable safety factor and torque key figures. The tool was designed to allow users to select the actuator more quickly and accurately in the engineering phase compared to conventional actuator selection.
