Metso has released Nelprof 6 expert valve sizing software to the North American marketplace. 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 new state-of-the-art tools in the program.

Nelprof 6 can be used to select all of Metso’s automated on/off and emergency valves. Performance analyses 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.

The new on/off valve sizing tool allows the selection of all Metso metal- and soft-seated on/off valves with advanced actuator sizing including adjustable safety factor and torque selection parameters. By using the tool, users can select actuators faster and more accurately in the engineering phase, compared to conventional actuator selection procedures, according to Metso. Generation of documentation as well as revision of the sizing is also possible whenever needed in the later phases of the selection process.
